I’ve been awaiting the molts of my two $5 Craigslist pink toe (Avicularia avicularia) tarantulas. Since I’m feeling more confident regarding gender determination using fresh exuvia, I decided to try doing so using an older exuvium.
I soaked an exoskeleton from its previous molt (12 weeks ago) for several minutes and then photographed it.
Not surprisingly, I did a little bit of damage opening it up, but the tarantula is clearly a young female. Still awaiting the molt of the other, stockier, heavier-bodied pink toe.
Thanks to Jen Newman (Heartland Invertebrates) and Paul Lawniczak for confirming gender of this individual.
