Arctia matronula

KANNAKSEN KAUHU

Hello everyone.

Out of interest, I would like to know has anyone else happened that A.matronula come straight through, meaning one of my larva did not overwinter at all. A wild female laid eggs last summer and the imago hatched on 7.3.26 after being a pupa for about 3 weeks. The larva was kept at room temperature the whole time and also under light 24/7 until January. I have not found any information on whether this species is prone to this, I think this does not happen with these larvae that overwinter twice in the wild, even if they are kept in light 24/7, and that is why I am now asking about your experiences with the species!?

Hi Jari,

That an Arctia matronula caterpillar didn't overwinter is certainly a rare exception. As you already mentioned, this species overwinters twice in the wild. In captivity, a single overwintering is necessary. However, the caterpillar must already be in its final instar.

Thanks for the reply Werner 👍🏼

Yes, it seems to be a pretty rare case. And what's strange is that now there's already a second pupa that should hatch into an adult in about a week 🙃
