I can imagen that could be the case with some on the old world tarantulas just like our
locals, as the male matures at a extremely small size.

The only thing about small females is that the alot easier to breed BUT they will make a
smaller egg sac and the stress on a smaller female is much more.

I've just learnt something new.

A.junodi is the only species other than P.muticus that I can think of that there is a serious size difference.
C.darlingi should also mature around 7cm as females and I have seen males and females over 15cm before, but suppose that is closer to the 50% mark.

Thanks guys!

Im just thinking haplopelma species. Dimitri couldnt believe his eyes when i should him
a mature male lividium. and they female was way larger than the male.

I know junodi male is tiny. I remember Scarab showing me a male and female comparrison and
the male could literally walk under the female and mate with her>

Check out Haplopelma minax male and female:
Don't be fooled. The male's leg is up against the glass making him look bigger.
