The round bottom of a Leucospid Wasp helps differentiate it from similar-looking mason bees.





While most wasps have abdomen that come to a point, this type of wasp seems to have rounded it out. They still possess stingers. Females also have an ovipositor, a syringe-like tube used for laying eggs in other bees and wasp nests. This ovipositor tends to curl instead of sticking straight out. Unlike other types of wasps that flare out their wings while resting, Leucospid Wasps will fold their wings on top of themselves, over their own generally hairless body. They have large 'thighs' on their hind legs, making it easy to mistake them for a bee with large pollen baskets.

This family of wasps is parasitic to a variety of other bees and wasps. The female will lay one or many fertilized eggs in an already existing nest. Once the first Leucospid Wasp hatches, it immediately sets out to eat every other egg in the nest, even if they are also Leucospid Wasps. It will pupate and emerge as a winged adult. Adults visit flowers all summer.

A Note About Territorial Reach: Keep in mind that an insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above. Insects are driven by environmental factors, food supplies and mating patterns and do not nescessarily work within hard-and-fast territorial lines like we humans do.
