Phyllonorycter ulmifoliella (Hübner, 1817) [Lepidoptera: Gracillariidae]. Tinea ulmifoliella Hübner, 1817. Samml. Europ. Schmett.: fig. 444. Phyllonorycter ulmifoliella (Hübner, 1817).

Leaf-mine: The larva forms a blotch mine on the underside of a leaf, often quite small, but puckering the leaf noticeably (UKMoths). The mine is 10-15 mm long, 1-6 creases in lower epidermis (British leafminers). 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 (Bladmineerders van Europa). Mines of Phyllonorycter ulmifoliella on Betula pubescens Image: Willem Ellis (Bladmineerders van Europa) Larva: Whtish, with an orange-yellow spot dorsally on the sixth abdominal segment. See Grandi (1931a, 1933a) for a description of the morphology (Bladmineerders van Europa). Pupa: The pupa is described and illustrated in Bladmineerders van Europa. Adult: The adult is illustrated in UKMoths. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.

Time of year - adults: Two generations, with adults flying in May and again in August (UKMoths).
