bluemoth: That's very interesting. Something similar happens in the case of Polythysana cinerascens. A fully developed male L5 larva is about the same size than a female L4 larva about to moult into L5.

I see. So the only way would be dissecting the poor caterpillar? :/

Dear people,
Is there a way to determine sex visually in lepidoptera larvae?
It's rather obvious in some species like the ones in the Polythysana genus, as males are way smaller than females, and you can note that in L4/L5 caterpillars, but what happens in species that size differences aren't that marked?

Hi to everyone. I found this larva in a corn. Is this Helicoverpa armigera? If so, can you tell by the pictures which instar it is? Basically I'd like to know if it's about to pupate. (Click on the pictures to see a larger version) Thanks in advance.

Wow... I'm totally speechless.
By the way, how expensive would be a regular sized X. heros specimen?

Oh yes, I already knew the species in my pictures But thanks anyway (the E. calleta is a female though, it's just a bit small ).

Very nice! I'm still very ignorant about most species, so forgive if I'm wrong, but my guess is that your specimens belong to the Rothschildia genus (?)
BTW, those eat Schinus molle? My Polythysana do so too! Seems like it's some kind of "wildcard" foodplant for many species.

Bill,
If I'm able to find any other Saturniidae I'll tell you in the moment.
As for Sphingidae, the only one I know in Chile is Manduca sexta. Its larvae used to eat my uncle's tomato plants. Of course if I ever find any I'll tell you immediately as well.

I see! This one didn't look as yellow as the one in your site, that's why I was doubtful about the species.
To be honest, I didn't even know I had this species in my house's surroundings. Now that I know I'll see how I can manage to catch a female. If I do, of course I'll be sending you any pictures you request me.

Today I went out to water my garden at 1:00 AM and noticed something was flitting around the light. I trapped it and resulted to be a Saturniid, but didn't know the species. I looked at WLSS and my guess is that it's a male Adetomeris erythrops, but I'd like someone to confirm it. Thanks in advance!
