Agrilus walsinghami
Agrilus walsinghami is a sexually dimorphic jewel beetle (family Buprestidae) found across western North America. It is among the most visually striking species in its genus, with males exhibiting bronzy-brown and brassy coloration while females are uniformly blue to greenish-blue. Adults are active during late summer and early fall, an unusual seasonality for wood-boring beetles in this region. The species is strongly associated with gray rabbitbrush (Ericameria nauseosa), which is presumed to serve as its larval host despite the absence of confirmed rearing records.
