Mompha raschkiella (Zeller, 1839) [Lepidoptera: Momphidae]. Elachista raschkiella Zeller, 1839. Isis: 211. Mompha raschkiella (Zeller, 1839).

Leaf-mine: A narrow gallery, often following the midrib, occasionally tinged red at the edges. This leads to a yellowish blotch containing dispersed frass (British leafminers). The oval, iridescent egg is deposited at the upperside of the leaf, mostly close to the midrib. Here starts a gallery, at first narrow and hardly widening, the first cm not always full depth, often making a few loops around the egg and/or running along the midrib for some distance. Parts of the leaf cut off by a corridor loop often turn red. Frass in small, grey grains, dispersed, not glued to floor or ceiling of the mine. Later the larva makes a full depth blotch; mostly in continuation to the corridor, but the larva can also leave the mine and restart elsewhere, which may happen already at this stage. A new mine begins with a hole where tha larva has gained entrance, end ends in an untidy exit. The larva lies venter-upwards in the mine. Pupation external (Bladmineerders van Europa). Mines of Mompha raschkiella on Chamerion angustifolium Image: Willem Ellis (Bladmineerders van Europa) The mine is also described and illustrated in UKMoths. Larva: The larva is described and illustrated in Bladmineerders van Europa. Pupa: On the ground amongst detritus (British leafminers). Adult: The adult is illustrated in UKMoths. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
