Asian Spotted Tortoise Beetle Larvae

Hi Võ Anh Tuấn, What a great spotting. I have some pictures of the larvae of Cassida circumdata which look similar, but have a darker coloured body and a wider "tail". They look so cute, but the "tail" catches their faeces and as they move around, they continuously flick it up over their back and down again. I think I read somewhere that this is to ward off predators and I know it works, because I have never touched another one since I found out about the "tail". John B.
