Cryptocheilus idoneum
Cryptocheilus idoneum is a species of spider wasp in the family Pompilidae, first described by Nathan Banks in 1910. Like other members of its genus, it is a solitary wasp that hunts spiders to provision nests for its larvae. The species has been documented in western North America, particularly in arid and semi-arid regions. Observations indicate adults visit flowering plants for nectar, including invasive saltcedar (Tamarix).
