When is a bee not a bee?

20th June 2012, Wednesday

When it’s the Red Data Book soldierfly Long-horned General (Stratiomys longicornis). The clue is the fact that this only has two wings (bees have four) and the antennae are made of only three segments (10 plus in bees). Still it’s a pretty good solitary bee mimic which had me fooled for a moment. You can also tell that this is a male due to the fact that eyes meet in the middle. In Britain this species largely occurs on the coast in the south-east, the larvae being associated with brackish pools. It’s a few years since I’ve seen it here (and there have been very few records) so it was nice to see this one outside Lime Kiln today feeding on biting stonecrop.
