I was just leaving my girlfriend's house to catch a bus this afternoon when I noticed this bee that seemed unable to fly, and it was over-grooming and acting as though it was dying. I did not recognise the bee (I enjoy studying Hymenoptera, but my ID ability is undeveloped), so I took a few photos to upload here. Much to my fascination and delight - though perhaps not the bee's - it had a Strepsipteran parasite, which is probably why it looked to be struggling. The photos are not perfect, but I hope they are clear enough for a species specific ID.
This was found in Brighton, East Sussex.
