Stratiomys potamida ♀ today in Bengeo garden. She has now been present here in woodland edge habitat for 40 days. In Europe, species' habitat is forest with small springs & narrow streams. Perhaps it is woodland species in UK that breeds in adjoining wet areas. Soldierflies RS

Robberflies enjoy landing on your camera hand. Normally any resulting photo is badly out-of-focus, occasionally they stay long enough for decent shot. Tolmerus atricapillus ♀ with Thereva sp. ♂ prey today in Bengeo garden. BNA – Herts branch #Asilidae #KiteTailedRobberfly #Stilettofly
