Microstylum morosum

Microstylum morosum

"Fear of commitment" - Mating Microstylum morosum, one of the giants of American Asilidae (robber flies). Occuring in two color forms and adaptable to both prairie and arboreal environments, morosum is one of the chief predators on large grasshoppers in the plains of the Panhandle. Formidable and efficient as a predator, the plains populations live a fragile existence intimately tied to the occurrence of certain localized shrubs which provide shelter from hostile weather elements of the Midwest. In flight, morosum resembles a large Pepsis wasp. Tesesquite Creek, Cimmaron County, Oklahoma
