Byctiscus betulae: leaf roll on  Tilia spec.

Tilia spec. © Belgium, prov. Antwerp, Balen, de Most, 28.iv.2017 © Carina Van Steenwinkel: fresh roll


In spring and autumn the adult beetles feed on the leaves, by shaving characteristic narrow strips of the upper side of the leaves. The female produces on average some 50 eggs, distributed over the 10-15 leaf rolls that she makes in her lifetime. For each roll she prepares a young shoot by gnawing a wound at its base, causing it to wilt. sometimes she also bits in the individual petioles on the shoot. As soon as the leaves have sufficiently lost their turgor she rolls 3-5 leaves together into s cigar-shaped roll, depositing sone eggs between the leaves. Normally the roll rather soon drops to the ground. The larvae develop in the roll; once full fed they crawl into the soil in order to pupate. After about two weeks a new generation of beetles appears.
