Curculionidae

This group, with their long rostrums (read noses) elbowed antennae and particularly rounded elytra comprise some of the beetles known as weevils. 

Lucky for us, there are few that are actively attracted to light, although a few species do occasionally turn up in traps. I suspect this is due to their 'tuck and drop' survival mechanism where they kamikaze from any foliage they happen to be on when threatened (or caught by a gust of wind).

Most weevils have a food plant preference, so it can be handy to know what trees are near your trap.

For everything Weevil, Mark Gurney is the go to guy, and he has written some AMAZING weevil guides.

They cost nothing, so make sure you make his time worth it and send him in your weevil records via IRecord
