I work outside..in Berkshire, England, UK.., and a few days ago i was using a bag of compost that had gotten a small hole in it at some point, and as i started emptying the compost bag i noticed bits of green leaves mixed in with the compost...odd, i thought!
On closer inspection though, they weren't just bits of leaves but perfectly formed little cocoons shaped like bullets, around 10 of them all together, each made from leaves that had been cut by some insect , wrapped and shaped into inch long 'bullets' complete with a sealed leaf cap on the end.
We opened one of the cocoons to find a fat little maggot-like grub inside...interesting!
I wonder what kind of insect these little grubs will grow into that makes such cool, perfect little bullet-shaped leaf cocoons?
Having done a little bit of detective work, i'm thinking they may be solitary bee larvae..any thoughts anyone?
