I found a couple of these sticking up out of the ground in a sandy place in my yard.
I have never seen them before. During the last week, I have seen a few robber flies at my porch light for the
first time this year, and I didn't know of any connection until I came across the Asilid pupal cases section
of robber flies on BG. An interesting example of complete metamorphosis. Among beetles, the pupal case resembles the adult beetle, but with this specimen, it's hard to see how a robber fly could have emerged from it.
