@etosaurus I'm not sure how common it is, but can assure you this species is *adorable*. Female feeds the male when she comes back with spiders. They are super fun to watch.
@cthululemon The emarginate (notched) eyes are one of the useful diagnostic features for this genus. Shows up in other wasps, too, though, so not unique. E.g., Scoliidae, Pison, probably many others. Here's another view from a past year.
