Mompha lacteella
(Stephens, 1834).


Leaf-miner: The larvae feed mainly on Broad-leaved Willowherb mining the leaves (UKMoths).

Large full depth blotch in the lower leaves. Much frass in coarse grains. The larva easily leaves its mine and restart elsewhere. Pupation either in the mine or in the ground. Mines cannot be told apart from those of Mompha propinquella (Bladmineerders van Europa).

Larva: The larvae of moths have a head capsule and chewing mouthparts with opposable mandibles (see video of a gracillarid larva feeding), six thoracic legs and abdominal legs (see examples).

Body varying from yellowish pink to purple brown; head black with a light V-shaped marking. Prothoracic plate black, divided lengthwise; anal plate and feet dark grey (Koster, 2002b; Koster and Sinev, 2003a) (Bladmineerders van Europa).

Pupa: The pupae of moths have visible head appendages, wings and legs which lie in sheaths (see examples).

See Patocka and Turcáni (2005a) (Bladmineerders van Europa).

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.
