|Wasp Beetle, Clytus arietis, caught on the outside of my window in Hayes on 4 June 2013.|
Later the same day, I saw another crawling on the outside of the window of my computer room! I snagged it the same way I do moths in summer, and this was the best of the resulting photos. They are fast and jerky movers, so it's not easy to get a closeup that is actually in focus and has the whole creature in the shot. I had to take lots. The fact that it's on the back of my left hand shows that I have had a lot of practice in wielding a heavy camera, macro lens and ring flash with just the right.
They are completely harmless to humans. Like the other beetles I have shown recently, they eat pollen from flowers. Their colouration is said to fool predators into thinking they are dangerous wasps; this is known as Batesian mimicry.
