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.<br />
For example, here is the (empty) cocoon of Hypera arator:<br />

Cionus tuberculosus is one of the small species of weevils in the tribe Cionini that have free living larvae on the plant's surface which are covered in slime for protection and create little cocoons of larval secretion.
