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 →
