Hypera arator - Cocoon
In 2011 I found this cocoon (just over the border in Germany( and took it home to see what would emerge (I had _no_ idea) ... turns out the cocoon of Hypera arator is very different from the cocoons of Hypera rumicis that I was already familiar with:
The weevils in the the subfamily Hyperinae are untypical for weevils in their development as the larvae are free living on the host plant's surface, much like most butterfly caterpillars. Most weevils develop underground or internally in the plant. The larvae also look a little bit like caterpillars. When these are ready to pupate they will create a cocoon made of secretions and pupate inside of it. The cocoons can be quite different in appearance and substance between species.
