(Male) Scoliid Wasp

Campsomeris sp.


I love this one! A beautiful Bee mimicking Wasp. Yellow and black striped abdomen and light yellow, fuzzy thorax and face. The wings are dark and eyes are gray as seen in picture 3. Wing tips of Scoliid Wasps are distinctively corrugated. "Males are more slender and elongate than females, with longer antennae, but the sexual dimorphism is not as extreme as is common in the Tiphiidae, a closely related family." - Wikipedia "Wings dark with wrinkles near outer margin. Head, thorax, legs, typically black or dark brown. Abdomen with yellow/dark banding or spots." - BugGuide


Mustard flower? at Lake Hodges. This genus is found throughout the US


Aka Scarab-hunter Wasp. "The females Campsomeris as well as other members of the subfamily Campsomerinae are predators on white grubs (Scarabaeidae), using these larvae 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." - BugGuide
