Bombus hypnorum in Shropshire.

The bumblebee Bombus hypnorum was first found in the UK in Hampshire in 2001. Since then it has rapidly spread, with a first record for Shropshire, from near Bridgnorth on the 5th June 2008.
The worker in the photograph had a full pollen load when caught, so she's from an active nest. She was nectaring on Comfrey - Symphytum species.
