We now offer bulk purchasing. More species will be added in the weeks and months ahead. Bulk purchase is available to everyone. The discounted prices will be less than can be achieved with the sliding scale. Moreover, all bulk purchases will apply to the sliding scale discount for non-bulk species. Feel free to ask whether a given species can be added to the bulk purchasing list. The list will always be in flux, depending on availability.
Tarantulas and other arachnids
Tarantulas and other arachnids from around the world. We supply hobbyists, breeders, and resellers from our rearing and breeding location here in Massachusetts. The majority of our species are imported from Germany on a regular basis. All imports are in accordance with USFW and US Customs regulations. As US captive-bred offspring become available we post them for sale, with prices that reflect the US CB advantage. We support responsible US breeding by providing guaranteed lineage, novel species, females, males, and breeding groups.
The hobby of tarantula keeping and breeding is moving quickly. As many of you know, numerous species have not yet been described. Others are in need of redescription. We use traditional scientific nomenclature for described and undescribed species. Unfortunately, errors in hobby-based nomenclature and identification are not uncommon. Common names, perpetuated seemingly by profiteers, introduce further confusion and error. One of our goals is to point out naming errors and inaccuracies where we find them, and help pave the way for scientific names to supercede whimsical common names.
Please check to see if a photo and text accompany the species in which you have interest. The paragraph(s) provide species-specific information and explain errors in naming and identification. The information used is collected from a variety of sources, typically overseas collectors, breeders, exporters, and arachnologists. Additional sources include hobby and arachnology textbooks, the Journal of the British Tarantula Society, and original scientific manuscripts. What we don’t know far exceeds what we do—we more than welcome information, including photographic, from any interested party. Credit will be assigned for facts and photos used in a posting, with permission granted of course.

For those of you new to the hobby, welcome! Here are a few tips to facilitate your venture into this exciting field:
There are many sources of reliable information, but time-tested The Tarantula Keepers Guide (TKG) by Stanley and Marguerite Schultz has helped thousands of hobbyists with the basics. It is worth reading before your first purchase.
Whether you are keeping one species or one hundred, spiderlings are generally the most economical investment. The main downside is a small increase in care requirements versus juveniles of the same species. It can take several months to raise a spiderling to the juvenile (Jv) stage. Understandably, many value this opportunity to observe the full life-cycle of a species.
Tarantulas aren’t easily sexed as spiderlings, but with increasing size, sexing by molt or ventral examination becomes easier and more reliable. Upon reaching reproductive age, or adulthood, males generally live for only another year. Females live for many more years depending on species. Collectors typically prefer females, whilst breeders obviously prefer both sexes. One unsexed spiderling has a roughly 50% chance of being female. Two increase the odds of one female to about 75%. With three the odds are close to 90%.
If you decide to purchase larger specimens, possibly to eventually pair with a tarantula already in your possession, you will notice we have different sizes of several species. After you have confirmed we have your species, you will want to know size. We prefer a single, anterior-posterior leg-span measurement with the spider in it’s most common position. Depending on instar, leg proportion, and species behavior however, a range measurement may better convey size. For example, a tarantula with a 4 cm body could be advertised as being 2″ (legs flexed), 2 1/2″ (legs partially extended), or 3″ (legs fully extended). In some cases we report a size range, from legs partially extended to legs fully extended. Both of these are necessarily soft endpoints, but they encompass the two methods most hobbyists use today.
With adult males (AM) we list molt dates when available, to the nearest month in most cases, to the day when known. Knowing when a male is penultimate, or subadult (SA), can be tricky. Don’t let anyone tell you otherwise. Size can be helpful, but exceptions abound. As with males, females sometimes mature at unexpected sizes. Upon sexual maturation, young adult females generally have potential to increase in size with further molts.
Unsexed juveniles here are truly unsexed, expect approximately 50:50 male:female. They are usually reared spiderlings that we haven’t gotten around to sexing yet and are often good bargains. As time allows, species lots of unsexed juveniles will be sexed and reposted in the sexed or breeding group categories.
Sliding-scale Volume Discount
We have added sliding-scale, volume discount purchasing. The more you buy the more you save. The scale starts with a 5% discount at $100. Higher discounts for larger purchases reach a maximum 25% for purchases of $300 or more. Discounts are automatically calculated by our shopping cart calculator when you add items to the cart.
We now offer bulk purchasing. More species will be added in the weeks and months ahead. Bulk purchasing is available to everyone. The discounted prices will be less than can be achieved with the same species and the sliding scale maximum. Moreover, bulk purchases will apply to the sliding scale discount for non-bulk species. Feel free to ask whether a given species can be added to the bulk purchasing list. The list will always be in flux, depending on availability.
Thank you, everyone.
