    I think perhaps the best way to help people learn to sex would be just to show photos of each gender. I will get the ball rolling. This is a female B. smithi.
    molt: [​IMG]

    Note the flap on the molt. Its the give-away for females. Absense of some sort of flap indicates a male, but remember to look closely! Some are tricky.
    ventrally: [​IMG]

    1. Males, especially more mature males may have a patch of somewhat thick hairs here.
    2. More of a lip (this is where males deposit sperm). Males sometimes appear to have a "hole".
    3. In comparison, females have a farther distance between the second book lungs.
    4. Males sometimes appear to have a "half circle" patch. It is absent here. Sorry, its asymetrical.
    The other two things have no significance, i just couldnt help myself :8o

    thanks for the pics becca. With the females you are looking for the flap on the molt. Look at all the female pics and you will find it on all the molt pics. I still have trouble with ventral shots, but with these shots i hope to get better and learn.

  19. Well, this is all peachy, however, all of you are forgetting one little MAJOR thing, not all tarantulas are female AND it's just as important for those new to the hobby to also be able to know and detect the epiandrous fusillae as well.
