The twig pruner, Elaphidionoides villosus, is a slender grayish-yellow, longhorned beetle about 1/2" long that is normally considered a secondary invader of declining trees and shrubs. The twig pruner attacks healthy twigs and small branches. The female lays an egg in the bark by slitting the surface at leaf axils in late spring. When these eggs hatch, the legless grubs bore into the twig.
