Megacyllene angulifera
Megacyllene angulifera is a longhorn beetle (Cerambycidae) native to central North America, ranging from Alberta to Texas. Adults are typically observed in fall on flowers of Solidago (goldenrod). Larvae develop in root crowns of Dalea candida (Fabaceae). The species is closely related to M. comanchei, with which it may be confused, though the two differ in elytral coloration, host plant associations, and adult behavior.
