Bombus hypnorum, the Tree bumblebee, comes in two forms - the dark form, seen above, and the more usual red backed form, seen below. It was first observed in the UK in 2001, being common in continental Europe, and now appears to be common here too.
This little critter, with a body about 1mm long, dropped dead on a windowsill.
This is a picture of the wing, at about 400x magnification. You can see the tiny hairs on the edge of the wing and all over it.
Here is the head and a leg - you can see the compound nature of the eye, plus hairs on the leg. Again at about 400x magnification.
