Klappentext

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Ash Bud Moth (Prays fraxinella) is a moth of the Yponomeutidae family. It is found in Europe. The wingspan is 14-18 mm. Adults are on wing from May to June and again in August in two generations depending on the location. The larvae feed on Fraxinus excelsior and Fraxinus ornus. They mine the leaves of their host plant. The mine consists of an irregular small corridor with dispersed black frass. Often the corridor widens in the end into an irregular blotch with much less frass. The mine may begin at an egg shell, but the larvae can leave their mine an start a new one elsewhere in the leaf. In the latter case the corridor begins with a small round opening. Before the leaf is shed the larva leaves the mine and bores into the bark, where it hibernates. After hibernation they live as shoot borer or free among spun leaves.
