Found a dead bumblebee on the garden path tonight and was about to dispose of it, when I noticed something peculiar - see for yourself:

Looks like the furry bastard didn't go down without a fight; those are the bodyless heads of 2 other bees (or wasps?) with their jaws still sunk into his wings :shock:

Never seen anything like this before. Is it normal behavoiur or should I be on the lookout for some kind of aggressive wasp/bees nest in the vicinity?
