Remarks
Eric Eaton has pointed out that there is considerable taxonomic confusion in Scoliidae, so that has to be a caveat in any photo identified as to genus here.
According to Nick Fensler: The females Campsomeris as well as other members of the Campsomerinae use white grubs (Scarabaeidae) as food for their young. Unlike sphecids, eumenines, and pompilids these wasps do not appear to have any type of prey transportation and dig to the ground-dwelling beetle larvae, sting it to paralyze it, and then lay an egg. They may dig around the grub to form a small cell. Since they use this nesting strategy they are often seen flying low to the ground (searching) in a figure eight pattern (but the flight pattern gets more erratic when they "smell" something). The adults use nectar as a food source and are common on flowers.
