Tenthredo basilaris

Tenthredo basilaris is a sawfly species in the family Tenthredinidae. Sawflies in this genus lack the narrow "wasp waist" characteristic of many other Hymenoptera, with the abdomen broadly attached to the thorax. Adults are often observed on flowers and consume both plant material and small insects. The species is part of a diverse genus containing approximately 118 species in the United States and Canada.
