Here is a wasp we have been seeing while walking around in dry areas around Riobamba, Ecuador (elev. 2800 metres). They seem to live in tunnels in the sand, and like to sit on plants (sucking on the stems?). They are quite big (maybe 5 or 6 cm). They look like nasty wasps, but don’t seem to be aggressive. Any ideas?

We are quite certain that this is a Scarab Hunter Wasp in the family Scolidae, and we believe it is in the genus Campsomeris. A North American species, Campsomeris quadrimaculata, looks nearly identical. BugGuide does not indicate if the range of this species extends to South America.
