Phyllonorycter ulmifoliella (Hübner, 1817)

red birch midget

Betula pubescens, Duin en Kruidberg

Betula pendula, Tilburg; opened mine of the summer generation: the cocoon is a flimsy spinning.

Betula pubescens, Hoenderloo, Hoge Veluwe: mine of the autumn generation

Betula pendula, Loonsche en Drunensche Duinen; opened mine of the autumn generation; the cocoon is so tough that opening it, with two pairs of tweezers, requires some force.

mine

Small lower surface tentiform mine; the lower epidermis is greenish yellow and weakly folded. Pupation within the mine in a cocoon that in the summer generation is so flimsy that sometimes it seems to be missing, while in the autumn generation it is quite tough. All frass in a corner of the mine.

host plants

Betulaceae, monophagous

Betula x alpestris, grossa, pendula, pubescens.

Reported by Hering (1957a) as an occasional miner of Ribes. The statement by Kollár (2007a) and Kollár & Hrubík (2009a) that the species were a pest on op Ulmus glabra and laevis must be due to a mistake.
