I've had several batches of Graellsia cocoons, and they've always arrived opened. If you were to use a digital scale,
make sure no plant debris was on the cocoons, you could probably get something close to accurate, they are a small
bodied moth with not a lot of difference in size, at least in my experience, the sexes may only be separated by a gram
Or so. With differences in rearing affecting weight, it would take several generations to get any kind of data
you could use. I suppose just by using basic numbers, any moth weighing 1 gram more than another would be a good
Guess at being female.

Hi Kevin,
Thank you for the helpful input!
Best, Marco
Ich weiß nicht, wie diese Kokons beschaffen sind, aber vielleicht kann man die Konturen der Puppen ganz gut erkennen, wenn man die Kokons gegen das Licht hält. Bei S. pavonia funktioniert das, und man kann die Puppen recht gut unterscheiden.
