Temnostoma balyras
Yellow-haired Falsehorn
Temnostoma balyras, commonly known as the Yellow-haired Falsehorn, is a syrphid fly species found in eastern North America. Adults are flower visitors that feed on nectar and pollen. The species exhibits elaborate mimicry of solitary mason wasps, including darkened wing margins and behavioral adaptations. Larvae develop in moist decayed wood, where they use thoracic hooks as rasping organs to burrow.
