Broad-necked Root Borer

Deciduous forests and woodlands throughout the eastern United States and southeastern Canada

Larvae feed on the roots of various living trees and shrubs; adults usually do not feed, focusing solely on reproduction

Nocturnal and often attracted to lights. They have a multi-year life cycle where larvae live underground for 3-4 years before emerging as adults in mid-summer

Generally harmless to humans but may deliver a painful pinch with mandibles if handled. Larvae can be minor pests of fruit trees and ornamental shrubs by damaging root systems
