insect hole

a bore hole, burrow, mine, passage, or tunnel in plant tissue, particularly wood or bark, made by an adult insect for mating, oviposition entry, emergence, or by a larva when feeding —note 1. the (mostly larval) tunnels of wood- and phloem-boring insects, sometimes packed with frass, are more commonly termed galleries and are generally made by wood borers, timber borers, shoot borers, bark beetles, or bark miners; bark beetles often form characteristic galleries that can be used in identification —note 2. if the insect takes wing more or less immediately after emergence, the hole is also called a flight hole —synonym emergence hole, gallery, mine, tunnel —see pinhole, shothole This definition last updated 10/28/2008
