Pyrrhalta viburni: oviposition on Viburnum opulus



Before oviposition the female gnaws a mm-sized hole at the underside of a first year shoot, deposits 5-8 eggs, then covers them with a voluminous wad that consists of a mix of frass and bark pulp. She repeats this several times, and often several females oviposits at the same spot, resulting in a long chain of ovipositions. The wads absorb rain water, which contributes to keep the eggs moist. The eggs hatch in spring; the larvae, at the underside of the leaves, first cause window feeding, later make small angular holes. They pupate in the soil in a cocoon made of dirt. In July the adults emerge, that make larger elongate holes in the leaves. Together with the larval feeding they can cause an almost total defoliation.
