Hi, I have hundreds of flies on my (rather neglected) lawn, hovering and walking in the grass. I think they are responsible for small holes about 3-4 mm where they have tunnelled in or out. Photo's attached. Could anyone advise what they are please?
These are wild bees in the Andrenidae family. See a few examples in this gallery: http://www.bwars.com/index.php?q=species_gallery (you need to click on 'bees', then on 'Andrenidae')
