Ten-lined June Beetle

Coniferous forests and sandy areas across Western North America.

Adults feed on the needles of coniferous trees; larvae (grubs) live underground and feed on the roots of shrubs and trees.

They are primarily nocturnal and are frequently attracted to porch lights. When disturbed, they produce a distinct hissing sound by pushing air through their spiracles.

Harmless to humans as they do not bite or sting. In high numbers, the larvae can be minor agricultural pests to roots, but they generally serve as an important food source for birds and mammals.
