Euathulus sp. “Red” or “Fire” is now Homeoemma Chilensis

Finally, our little hobby darlings drop the “species” label (and find themselves in a new genus)

The new paper, First record of Homoeomma Ausserer, 1871 in Chile and description of two new species (Araneae, Theraphosidae) by Rubén Montenegro V., Milenko A. Aguilera & María Eugenia Casanueva brings with it significant changes for two of the hobby’s favorite little dwarf tarantulas.

  • The species originally referred to as Eauthlus sp. “Red” or “Fire” is now Homoeomma sp. chilensis.
  • The species originally referred to as Euathlus sp. “Yellow” is now Homoeomma orellanai.

For those who have been in the hobby for a while, this news isn’t exactly shocking. Euathlus has long served as a bit of a “place holder” genus for spiders who have not been adequately described. The hobby staple, Brachypelma hamorii, for example, was once Euathlus smithi. It has long been thought that this species would be moved into the genus Homoeomma once it was properly studied and examined, and many vendors had already begun labeling them as Homoeomma sp. fire.
Now, for changes like this to become truly “official”, the paper has to be published, peer reviewed, and accepted by the scientific community. With the paper having just been published this month, I’m not sure if this has happened yet. However, as with all name changes, word will spread quickly and many will have questions as to why this species is suddenly listed under another name. Vendors may also change the names on their websites, which can lead to some confusion.
Personally, I’m excited about this new development. Anytime species get properly described, it’s a good thing for science AND the hobby. As always, there will be some folks who are reluctant to adopt the new name due mostly to sentimentality and a misunderstanding of how scientific names and species identifications work. I know of a couple folks who refuse to call the species formerly known in the hobby as “B. smithi” the correct name of “B. hamorii.” Still, it’s important for folks to understand and appreciate that a name change, although jarring and confusing at first, is a sign that these creatures are getting much needed attention from taxonomists and the scientific community.
I would encourage anyone interested in this change to read the accompanying paper. Along with the reclassification of these two species were a couple other very interesting informational nuggets.

Interesting Tidbits:

  • These will be the first two Homoeomma species to be found in the country of Chile. Previously, this genus was known to be found in Brazil, Uruguay, Colombia, Argentina and Peru.
  • In the wild, H. chilensis was found in shallow burrows beneath rocks and under tree trunks. Burrows were generally no deeper than around 5 cm.
  • They were observed eating ground beetles, wasps, and other spiders.
  • Possibly the most interesting revelation is that H. chilensis adults were found to occupy burrows in close proximity to other adults, sometimes mere centimeters apart. One particularly fascinating photo included in the papers shows three burrows in about a 1 square foot area.

Generally, once a paper is widely accepted, the changes will be reflected in the World Spider Catalog . Those who want to follow the progress of this new development will want to check in there.

Caribena versicolor (Antilles pinktoe) Breeding Notes … and Babies!

Spoiler: The Breeding Was a Success!

For those interested in possibly breeding the Caribena versicolor in the future, here is an account of my pairing. All in all, it was a rather simple endeavor from start to finish, and I would encourage others to try it. And for those looking to acquire some of these little blue beauties, be sure to read to the bottom of the article…

The Pairing – November 26, 2017

In November of 2018, I paired my mature female Caribena versicolor with a mature male lent to me by Tanya at Fear Not Tarantulas. I had raised this female from a sling, and she is currently about 5 years old. She was fed very well leading up to the pairing and was quite plump before the breeding attempt. I have never attempted to breed her before this pairing.

Upon opening both enclosures, the male, who was incredibly active, came right out and approached the female within 30 seconds. The female appeared startled at first, and a quick “scuffle” ensued which caused the male to back off for a few moments. However, he quickly regrouped and approached her again, and she was very receptive. After a very brief courtship in which they entangled legs and the male tapped on her a bit, they coupled. I observed two insertions before the two disentangled and the male calmly walked away. I did not try to pair them a second time, as I was pretty sure the first pairing was successful.

The entire event took only about 5 minutes total from beginning to end. The female showed no aggression toward the male and did not try to consume or pursue him when they had finished.

The Female Makes a Sac – December 27, 2017

About two days after the pairing, the female webbed herself up completely in a funnel web down the side of the enclosure. Although she had webbed up a bit of a “chamber” for her last molt, she thickened the sides, especially on the Plexiglas, and closed off the ends. I tried offering her crickets the day after she was bred, but she showed no interest in eating.

Caribena versicolor

On December 28th, I noticed that she had finally created an egg sac. This sac was about 1″ in diameter. During the incubation period, I kept her enclosure on a high shelf that ranged in temperature from about 78° F to 80°F.  I kept her water dish full, and once a week I would open the enclosure and use a large bottle with holes in the top to simulate a rain shower. I would use this technique to moisten part of the substrate so that enclosure wouldn’t become too dry.

For this breeding, I chose not to pull the sac and instead left it with the mother. She continued to care for it perfectly during the incubation period, constantly rolling and moving it to keep the eggs from sticking or getting crushed. She was an excellent mother throughout the entire process.

2nd Instar Spiderlings Emerge – February 18, 2018

Finally, I came down on the morning of February 18th to find that several little blue 2nd instar slings had emerged. Over the next three days, the rest of the brood freed itself of the sac, and little blue spiderlings lined the entire inside of their mother’s web den.  Instead of immediately spreading out and leaving the web, the slings huddled together while the mother stood over them.

As the mother’s enclosure offered several means of escape for the tiny slings, including gaps and vent holes, I had to sling-proof it before any of the little ones could get away. I used some cheesecloth and clear cellophane tape to cover up the vents and gaps. The cheesecloth kept the slings inside without restricting ventilation.

Despite my best efforts, I apparently missed a corner, and I woke up one morning to find a sling’s toe poking from the breach. With the slings now starting to spread out and wander a bit, it was time to separate and house them.

Separated and Rehoused the Slings – February 21, 2018

We started by carefully opening the cage and removing the mother. Using a paintbrush, I coaxed her away from the slings and into a deli cup. Although she was reluctant to move, she did not become defensive or nasty. With mom out of the way,  Billie and I spent the next hour getting the slings out of the web and into their enclosures (dram bottles and small deli cups). Fortunately, the slings didn’t attempt to scatter, but instead congregated in groups as they tried to hide. This made things MUCH easier. We had placed the mother’s enclosure inside a large Sterilite container in case the babies tried to bolt, but it never became an issue.

When all was said and done, we had 148 lively slings! Being 2nd instar, the slings were very active and ready to eat. I gave the ones I kept a couple days to settle in and to start webbing before offering the first meal. For the first feeding, I used pinhead red runner roaches, which I prekilled and dropped in each sling’s webbing. So far, all have eaten twice.

Versi Babies for Sale!

Unfortunately, with all I have going on with the blog, YouTube channel, and now my podcast, I don’t have the extra time I would need to raise and sell my own slings. Although several folks have inquired about buying directly from me, that’s just not practical for me at this time. However, for those who want to get their hands on a couple of these gorgeous blue slings, you’re not out of luck.

A few days after the slings were rehoused, we got a visit from Tanya Stewart and Rachael Pan from Fear Not Tarantulas. They picked up all but a few of the baby C. versicolors (I held onto five for myself), and they will selling them online from their store and at expos. Tanya is a very well-respected and trusted dealer in the hobby, and folks will have the option of getting more for their shipping money by possibly ordering other species from her diverse selection.  Even better, Fear Not is offering 15% off the price of a C. versicolor sling if you use the code “tom” at checkout. C. versicolor are always in demand, and the slings are going fast, so be sure not to wait too long if you want to grab one.

Moving ahead, I will continue to pursue breeding projects that interest me and with species there is a demand for.  At the moment, I’m hoping to have my M. balfouri and H. pulchripes both bred after what appeared to be successful pairings. I will obviously keep folks updated if and when anything develops!

‘T’ Time Adoption/Rescue Facebook Group- And Interview with Samantha Miller

A brand new group hoping to fill a much needed hole in the hobby. 

Several years back, I got an email from a frantic hobbyist who was preparing to start his freshman year in college. With only a few weeks to go before he was to move into his dorm, he made an unfortunate discovery; this particular school didn’t allow any pets in the freshman dorm rooms. This young man had amassed a modest collection of a half-dozen or so tarantulas, and his mother, an arachnophobe, had already made it quite clear that the animals couldn’t be left behind. Instead of enjoying his last remaining days before starting school, this poor guy was desperately trying to find a new home for his beloved pets. He was even willing to part with them for free if they went to a good home, and he was hoping I might know of some place that would be willing to take his collection and ensure his animals got the proper care.

Over the years, I’ve received several similar emails from hobbyists looking for someone to adopt their pets, and I’ve usually directed them to the classifieds section of Arachnoboards or FaunaClassifieds. The truth is, although there are obviously a plethora of options for folks keeping warm-blooded vertebrates like cats, dogs, ferrets, etcetera, the options for invertebrate keepers are quite limited. Although a few shelters will take in the oddball invert, most know little about their care or are particularly interested in dealing with the “creepy crawlies.” I’ve heard of cases of people with one or two spiders donating them to a school science teacher or a friend or family member, but what does one do when she has several spiders? Or, perhaps someone has outgrown the hobby and recognizes that he no longer has the passion to keep these animals. Where should he go to get them new homes? Sure, Craigslist and the classifieds can work, but selling off larger collections can take time…and emergency situations can lead to strict deadlines.

Then there are hoarding cases or instances in which a keeper dies leaving behind dozens of pets that no one wants or knows how to care for. What happens to these animals after being confiscated by the authorities?

Well, now there may be a new option.

While chatting with hobbyist Samantha Miller, I learned about her idea to create an adoption and rescue service specifically for inverts. Within weeks, she had set up the ‘T’ Time Adoption/Rescue group on Facebook in an effort to see her idea come to fruition. With the membership numbers swelling and the group off to quite the auspicious beginning, I caught up with Samantha to learn more about this fantastic and much-needed new group.

Thanks for taking the time to chat, Samantha! Continue reading

Tom’s Big Spiders – The Podcast

After much debate, I’ve decided to start a weekly podcast about tarantulas and other arachnids. I had been asked about starting a podcast a few times over the years, and as I really didn’t know too much about them, I scoffed at the idea. I just couldn’t imagine I would have enough to say to make one interesting, or that folks would be even remotely interested in hearing it. I know it may sound in my videos like I love hearing myself talk, but I can’t stand the sound of my own voice (really, who does?).

But after a recent discussion with my brother, an admitted podcast junkie, and another chat with a keeper, I decided to do a bit of research to see if it was a realistic outlet for me. For the past several months, I’ve been making a list of possible topics as well as folks I would like to either work with or interview. As luck would have it, I’ve been doing much more voiceover work in my YouTube videos as of late, so I have also gotten some good experience with talking and staying on subject.

Last month, I asked some of my friends on Facebook if this was something I should pursue, and the reaction was very positive. It seems that there are a lot of hobbyists out there that like podcasts, and not a whole lot of people doing them. Excited by the possibility of branching out into new media, I signed up for a plan, downloaded some programs, and sat down to test it out.

So far, I’m loving it.

Many times when putting the videos together, I have to shorten my explanations because I don’t have enough footage to accommodate for all of the dialog. I’ve found that recording the podcasts allows me to go into much more detail with the discussion. There are also topics that might not make for the most interesting videos or articles that might be better delivered in a more conversational format. Even better, this format would make interviews much more natural and easier for the interviewees.

It won’t replace my articles or videos, but I do believe the format will allow for another excellent outlet for tarantula information.

To start, I will be releasing one 30-minute episode every week on Sunday. As I know folks that follow podcasts like them to be released consistently, I’m recording several ahead of time to start so that I will always have one ready to go even if life intervenes. As I get more comfortable with the format and schedule, I’ll look to start mixing in interviews and even live episodes. If all goes well, they will be available on both iTunes and Google Play as well.

Below is my first “pilot” episode in which I field a question about feeding dead prey to tarantulas and discuss shipping in the winter, as well as a bonus episode featuring a Q & A. I’m also including a link to my podcast page. Hopefully you all find it enjoyable and continue to check out future installments. I’ve got some cool ideas going forward, and I think that I’ll continue to improve with each outing.

Harpactira Genus – Husbandry Notes

Harpactira Husbandry Notes (ft. H. baviana, H. cafreriana, H. hamiltoni, and H. pulchripes)

Gorgeous “baboon tarantulas” from South Africa, Harpactira species have become much more prevalent in the hobby as of late, with many vendors offering a variety of slings for sale. Recently, there have been more Harpactira species available than ever, their newfound popularity possibly spurred by the introduction of the gorgeous and highly-desirable Harpactira pulchripes or “Golden blue-legged baboon.”

These mid-sized Old Words sport a variety of pretty ambers, golds, bronzes, and even a bit of green. My first experience with this genus came with the aforementioned H. pulchripes. Back in 2015, I acquired a sling and a juvenile female, and I immediately fell in love with the species. Besides their strikingly good looks, I found this spider to be incredibly hardy with a fairly laid back temperament for a baboon species. Last year, I was fortunate enough to get several more Harpactira species from Tanya at Fear Not Tarantulas, and I have become a huge fan of the genus. Connoisseurs  of heavy-webbing, visible, fast-growing, robust, pretty baboons will find a lot to love about this genus.

SLINGS

Species from this genus start out rather petite, so folks may find that smaller dram vials or 4-oz deli cups will provide good sling enclosures for smaller specimens. For slightly larger specimens ( .75″ or larger), the tried-and-true 16-oz deli cups make great homes. I’ve used all three types with no issues, so a keeper can use his or her discretion when selecting its first home. My specimens are more webbers than burrowers in most instances (although they may still dig), so provide a bit of substrate and piece of cork bark for a hide. If possible, also include a fake leaf or two to serve as an anchor point for webbing. Mine all immediately took refuge beneath the cork bark, using this as the epicenter for their silk. This also gives them a place to retreat to if they are startled so that they don’t bolt out of their enclosures. One of the only tarantula escapes I’ve ever had was a Harpactira pulchripes sling that I got sloppy with during a rehousing. It was up my arm and around my back in a blink. Although I’ve found slings from this genus to be more calm overall than most baboons, they can still be skittish and are very fast. It would behoove hobbyists to keep this in mind when working with them. Continue reading

Tarantula Hybridization in the Hobby (Tarantula Controversies #5)

It’s one of the hobby’s most hot-button topics, and one that elicits spirited and emotional responses from both sides of the argument. For many, the topic of hybridization is a fascinating one, and curious hobbyists hear about hybrids and want to find out more about them. Unfortunately, any public inquiries in the hows, whys, and why nots of a potential mixing of species swiftly erupt into heated arguments and debates.

On the one hand, there are the folks that don’t think tarantula hybrids are that big of a deal, with some even expressing that a keeper can do whatever he wants with his spiders, as long as they aren’t sold into the hobby. Many of these keepers believe that the supposed problem of hybridization in the hobby is over exaggerated and that those who are staunchly opposed to it are alarmists.

Others find the idea of purposely crossing species appalling and unforgivably irresponsible under any circumstance. Many of the people on this side believe that hybrids are prevalent enough in the hobby to seriously compromise the purity of many bloodlines. Any attempt to knowingly breed them is a gross disservice to the hobby and, in some cases, a Frankensteinian perversion of nature.

Recently, I was emailed by a young man who was new to the hobby and eager to discuss some of his experiences with a more seasoned keeper. During our exchange, he mentioned that he had managed to obtain a mature female Brachypelms vagans as well as a mature male Brachypelma albopilosom. He really wanted to breed but was having difficulty acquiring a male for his vagans, so he came up with the idea of trying to crossbreed the two species to get, “a cool designer tarantula.” What ensued was a lengthy back-and-forth email discussion about tarantula hybridization and why it is a detriment to the hobby.

It can be difficult for new and casual hobbyists to understand why hybridization is so frowned upon by many serious hobbyists. Even after several emails, this young man still didn’t seem to fully grasp why this practice was considered taboo by many. As I’ve encountered this question many times myself, I thought it was time to tackle the topic in hopes of educating folks who may not understand why it is such a controversial issue.

Below are the arguments and counter arguments and how they usually break down. For clarity, stances supporting hybridization will be in GREEN; stances against will be in RED. Continue reading

Tarantula Sling Care Guide – The Video Version

A picture is worth a thousand words…

When I first became hooked by the hobby, I literally had to be convinced by a vendor to pick up my first spiderlings. True story.

At the time, I was looking for sexed juveniles and adults, and the thought of caring for a tiny, fragile ‘sling was terrifying to me. What would I feed it? How should I give it water? What if the temperature in my house was too low? A thousand daunting scenarios played through my mind, and almost all of them ended with a dead spider.

When I finally took the plunge and ordered my first two 3/4″ slings, I remember the feeling of dread I had waiting for them to be delivered. I was convinced that I had bit off more than I could chew, and now there was no turning back. When they arrived, I fussed over their enclosures, fixated on their burrowing and webbing habits, just about developed an ulcer when one buried itself, and panicked when they inevitably refused meals. I also spent hours on Google researching each seemingly odd or worrisome behavior for some type of reassurance that I wasn’t screwing up. Continue reading

Have You Ever Been Bit By a Tarantula? A Survey

If you’re a hobbyist, please take a few seconds to participate!

Okay, I’m hoping to get as much participation as possible on this, so my sincere thanks to anyone who takes  a moment to answer or share these two polls.

The first question pertains to whether or not you’ve ever experienced a bite under any circumstances. I hear a lot of folks, mostly those new to the hobby, make statements like, “it’s only a matter of time until I get bit.” Do bites happen? Sure. But my belief is that they are not very common. So, who out there has experienced the business end of a tarantula?

Dolichothele diamantinensis “Brazilian Blue Beauty” Care

Dolichothele diamantinensis  “Brazilian Blue Dwarf Beauty” Husbandry Notes

When I first got into the hobby, I tended to ignore some of the smaller species. I was basically obsessed with larger Ts, and most of my wish lists were filled with the giant species with leg spans of 7″ or more. At that time, I didn’t get some keepers’ obsessions with the so-called “dwarf” species. Wasn’t the point of keeping big spiders to show off species that were larger than your common garden spider? However, as my collection grew and I obtained more spiders, I matured a bit and let go of my anti-dwarf prejudices. I started to seek out smaller species like B. cabocla and dwarfs like Euathlus sp. red and Hapalopus sp. Colombia larges. It quickly became apparent that by shying away from the more diminutive species, I was missing out on some amazing animals.

After seeing some photos of the D. diamantinensis, I immediately moved this small species to the top of my wish list. These gorgeous, highly sought after spiders looked like miniature GBBs with their blues, greens, and a touch of red. Unfortunately, the first slings in the US were quite pricey, so I decided to wait it out a bit until prices fell. Finally, in December of 2016, I received three gorgeous little slings from Tanya at Fear Not Tarantulas with the polite warning that they were very fast.

She wasn’t kidding.

These little guys are quite speedy as slings, and keepers should take precautions before transferring or rehousing them to prevent escapes. I pride myself on my ability to transfer spiders without incident, and these little spitfires gave me a run for my money. Continue reading

Psalmopoeus irminia “Venezuelan suntiger)” Husbandry Notes

A gorgeous, if somewhat reclusive, arboreal.

Years ago when I was getting serious about tarantulas and researching which species were currently available, I stumbled upon this gorgeous black spider with orange highlights on its legs and abdomen. Besides being an amazing looking spider (I’m a sucker for orange) it had one of the coolest common names I had heard…the “Venezuelan suntiger.” However, as I was new to the hobby, I was turned off to this species when I read that this arboreal was fast, skittish, and could have quite the attitude. For a while, I forgot about it as I became more interested in calmer, slower-moving terrestrials.

Fast forward several years…

P. irminia (c) Dallas Beck

After receiving a Psalmopoeus cambridgei as a freebie, I immediately developed more of an appreciation for arboreal tarantulas other than ones in the Poecilotheria genus. Eager to add some new tree spiders to my collection, I was again reminded of the P. irminia. I was more than ready for this spider now, so when I saw that Tanya at Fear Not Tarantulas had a juvenile female listed, I jumped at it. Continue reading
