It really is an amazing thing to see, I got to see my B.albopilosum and B.smithi molt. I find the difference in their moltings is rather interesting, the curly hairs was like a very brittle paper(it nearly doubled in size) it also flew out of my hands when I breathed within a foot of it. Whereas the red knee's molt seemed to be a bit thicker, still light but not as much as the curly hairs.

Save that exuvium and we'll see if you got a boy or girl.

My X.immanis just molted too and from the molt it looks like a male.:mad:
I'm going to go look at this one right away.

Just had a look,unfortunately it was ripped in half right though the epigastric furrow.Maybe next time.

Educate me, please. How do you sex a tarantula with the molt?

Educate me, please. How do you sex a tarantula with the molt?

Between the forward set of book lungs is a line called the epigastric furrow. This is where the male deposits the sperm into a female and where the sperm is extruded in a male. Both sexes have this furrow but when you look at the furrow from the inside, which you can do if you have a well preserved exuvium, you will find a flap or leaf like structure in the female. This is where the sperm is deposited. This structure does not occur in the male. By using magnification and sometimes a microscope, the sex of a tarantula can be determined at an early age. Sometimes.

Here's a link to a thread that explains this all in much more detail and with pictures too!


The shape of this leaf like structure and its accompanying spermathecae and the shape of the males emboli are two of the major features that determine the species of any particular tarantula. The males emboli have to be just the right shape to be able to deposit the sperm into the female.
