The curious sweeping action of the long front legs of this fly wandering back and forth on a dead elm caught my eye at Sandy Smith NR this afternoon. Once snapped the amazing eyes also became evident. A bit a googling suggests it may be a female common cleg Haematopota pluvialis?
Nearby on an umbellifer was a chafer beetle being blown around hampering photography (my excluse for it being blurry). More googling suggests the Welsh Chafer Hoplia philanthus which the NBN Gateway shows has a sparse distribution without any Bedfordshire dots on the map?
In the floor of the pit is an aggregation of Oxybelus uniglumis nests, with flies impaled on the sting arriving frequently, a quick burrow clearance with the front legs and they are quickly stashed.
