Hi
Who can help me?[Blockierte Grafik: webkit-fake-url://CEA5E7E6-31F8-4F1B-8845-F10D8F92BB62/imagejpeg]

Hi
I hope that you can see him now!
Otherwise I might be abel to describe him.
The egg was round and yellow, with a small brown dot at the top.
The caterpillar is Brown-black, but its back is white.
Just behind its head It has 2 hairy white horns pionting ahead.
It's overall slightly haired, but its head is bold and black.
It is a tropical caterpillar.
I found the eggs in a zoo, and because I know they destroy them if they find them (they get all their butterflies out of cocoons), did I decide to take them with me.

Thanks in advance
Christiaan
