The species is notable for its specialized larval biology: caterpillars bore into and feed within the cones of fir and Douglas-fir trees. Adults are active across multiple months from spring through fall, with records spanning March through October. The species has been documented visiting apple flowers at night, contributing to nocturnal pollination services.
