Casey's June Beetle (Dinacoma caseyi)
Where Listed: WHEREVER FOUND
Casey's June beetle belongs to the scarab family (Scarabidae). The genus Dinacoma includes two described species, D. caseyi and D. marginata (Blaisdell 1930, pp. 171-176). The Casey's June beetle was first collected in the City of Palm Springs, California, in 1916, and was later described by Blaisdell (1930, pp. 174-176) based on male specimens. This species measures 0.55 to 0.71 inches (in) (1.4 to 1.8 centimeters (cm)) long, with dusty brown or whitish coloring, and brown and cream longitudinal stripes on the elytra (wing covers and back). Based on surveys conducted to assess the species' presence, both male and female Casey's June beetles emerge from underground burrows sometime between late March and early June, with abundance peaks generally occurring in April and May (Duff 1990, p. 3; Barrows 1998, p. 1). Females are always observed on the ground and are considered flightless (Duff 1990, p. 4; Frank Hovore and Associates 1995, p. 7; Hovore 2003, p. 3). Males are reported to fly back and forth or crawl on the ground where a female beetle has been detected (Duff 1990, p. 3). Cornett (2003, p. 5) theorized that after emergence, females remain on the ground and release pheromones to attract flying males. After mating, females return to their burrows or dig a new burrow and deposit eggs.
