Hi, I have been a big fan of your site for many years! There is some type of ground-burrowing wasp with blue wings that makes a nest in my yard every year. I usually see activity (little piles of dirt) around May, and by June or so it always seems like the nest is abandoned, and I never see any more signs of life until the following year. The nest spot in the ground is a patch about 2′ x 2′ with multiple holes.
This year, the nest seems larger, and there has been lots of activity. The creatures are about 1″ long, have blue wings, black bodies, and fat legs – especially the “hind” legs.
So far, they do not seem to be aggressive, but I would love to find out more about them.
Thanks!

Dear Harry,
We believe these are Mining Bees in the genus
Andrena, and the closest match we were able to locate on BugGuide, from nearby Virginia, is the Dusky Winged Andrena, Andrena obscuripennis.
