The Bee fly Bombylius Major. This photo is from last year, though I`ve alredy seen a couple this spring. They can be seen hovering in front of flowers, steadying themselves by just resting their legs on the petals. Seen against the light the apparently sturdy beelike body turns out to be mostly an array of bottlebrush- style bristles around a rather weedy abdomen. All proboscis and trousers!
