Biology
The caterpillars develop on Genuine hops ( Humulus lupulus), Japanese hops ( Humulus scandens ) and Boehmeria nipononivea. The females lay eggs on the midrib or other large veins of the leaves. Due to the feeding activity of young caterpillars emerging along the leaf veins an irregular oblong mine with a silky burrow. It serves the caterpillar as a shelter if they do not eat. Based on this passage lay the crawler later branching in all directions to, so that a highly irregular, yellowish white place mine arises is distributed in the Raupenkot. The caterpillars can change mine, in large leaves also several mines may be present. The caterpillars can be found from July to September. In the fall customize an elongate white cocoon and overwinter in the debris on the ground. The moths fly from May to July and can be knocked out of the host plants.
