found on coastal grassland
No interactions present.
Can you say more about this charlie, are these larvae or pupae? I didn't know weevils spun silk into this sort of cocoon.

Sorry, I meant to add a comment to this... I've found similar structures before, and tentatively ID'd them as weevil pupa/cocoon - but none that I have collected have yet to emerge.
Hypera postica is a good example, or search for "weevil cocoon".
I think some chrysomelids do something similar.
I'd tend to agree that it's a weevil cocoon, though I've not seen one exactly like this photo.
Thanks for the useful info. I will keep an eye out for more this season and try to get some better pictures.
