Tarantulas (Aphonopelma hentzi, Theraphosidae) have a high profile due to their popularity as pets, larger size, ease of recognition, and the wandering habits of the males. In addition, their delayed sexual maturity ( up to 10 years), long life span (20Ð30 years), and appeal as pets places them at a higher risk for extinction than other invertebrates. However, very little is known regarding the abundance and distribution of tarantulas in Missouri. Generally, they are believed to be limited to glades and dry woodlands primarily in the southwestern portion of the state. Yet, they have been noted as far east as Jefferson County. Unfortunately, most of the data regarding tarantulas in Missouri have been derived from casual observations, speculation, and anecdote. To date there has been no systematic assessment of the distribution of this family in Missouri, even though these spiders are by far the largest in the state.
As part of my Ph.D. dissertation at the University of Missouri-Columbia, I would like to construct a distribution map of tarantulas in Missouri based upon recent and past field observations from as many reliable sources as possible. As a result, I am requesting anyone with first hand knowledge regarding presence of tarantulas in Missouri to send me the following information:
date observed (as specific as possible), location (as specific as possible), the number of sightings per year (if applicable), and contact information of contributor.I can receive information via e-mail (tarantula@missouri.edu), phone (573-882-3037) or postal service:
