Juniper Webworm (Daeborneris Marginella)

Juniper Webworm has only one generation per year. The adults emerge in May/June, and only live for about two weeks to mate (what a life). The eggs hatch in about 10 days, but 50-200 eggs are laid by each female! The larvae feed inside the leaf (leafminers) then exit and form tiny silken tubes, in which they live in from summer through winter. Then in very early spring they feed heavily on top of the leaves in larger webbed communities. They effect horzontalis, depressa, and many different Chinese junipers. Leaves, of the effected junipers, turn brown (summer-winter) and/or are defoliated (spring).
