dorbug (DOR-bug) - n., any of various beetles that fly with a buzzing/droning sound, esp. a) a common European dung beetle (Geotrupes stercorarius) and b) any of various American beetles also called June bugs.

The June bugs are varied -- the name encompasses the green June beetle (Cotinis nitida) of the southeastern US, the ten-lined June beetle (Polyphylla decemlineata) of the western US and Canada, the figeater beetle (Cotinis mutabilis) of the southwestern US, and the genus Phyllophaga (with over 900 members). The figeater is local to me:

The dor- part goes back to Middle English dorre/dore, from Old English dora, bumblebee, akin to Middle Low German dorte, drone, Old English drān, drone.
