Hi everyone, I'm new here and would like to know about the sexual dimorphism of Papilio krishna krishna. The pictures of Yukio Shimogori in "Achillides Butterflies" don't show big differences on the upper wings of both males and females. Thank you!  |

That's because there isn't a very large difference between male and female of Papilio krishna. The female is larger with slightly more rounded wings, the pale fw band is slightly more diffuse and the red hw discal rings are better developed.
Adam.

First, welcome aboard 'crino'..
Adam answered you fine, but in case it helps, sexual dimorph. occurs where the males and females are colored differently(look almost like different species). The krishna species is not at all sexually dimorphic like the Speyeria diana etc.

thank you! When I have set the 2 P. krishna krishna I've recently got, I'll post the pictures and maybe you can help me to find out who is who... It is supposed to be a pair. I imagine this one (ssp. charlesi from China) is a male. Greetings Attachments:

A graphic description of claspers was originally filed by DeVries in his books,
although they relate to Costa Rica.
As Adam says the same applies to krishna.

thanks, the pictures posted by Adam are very helpful! Here is a pic of its abdomen of the charlesi. When I have time to spread the pair krishna krishna I'll be able to compare their wings and abdomens. Then I'll post the pictures. With a newborn at home I haven't got much time for all this...  Greetings  |

I know what you mean about a newborn, congratulations! My son is 7 weeks old too.
Your charlesi is clearly a male.
Adam.

Despite being 52 already, my 7 week old son is my first child. Currently he's only interested in milk, but maybe that will change with time ;-)
Hopefully my son will like insects, but I think the best approach is to guide him gently and not be disappointed if he is not interested, as everyone has their own life. Certainly, the worst approach is to try to force him to like something, that rarely works.
Good luck,
Adam.
