Calamotropha paludella (Hübner, 1824)
[Lepidoptera: Crambidae]

Bulrush Veneer


Tinea paludella Hübner, 1824. Samml. Europ. Schmett.: 452-3, pl. 88
Calamotropha paludella
(Hübner, 1824).


Leaf-miner: The slender larva mines the leaves, stems and upper rootstock (UKMoths). Oviposiiton at the leaf margin. From here the larva bores into the leaf tissue, and makes a descending mine that contains much brown frass. The larva hibernates in the lowest part of the mine or in a cavity gnawn in the rootstock. After the winter it mines again in the, by now, dead leaf or in the stem. Pupation internal (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).

The larva is illustrated in UKMoths. Body yellowish brown; all segments bear two greyish brown shields, one behind the other, in fact strongly enlarged and fused pinacula. Head and prothoracic plate shinign light brown, anal plate right brown (Bladmineerders van Europa).

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

Adult: The adult is illustrated in UKMoths and the Encyclopedia of Life. The male and female genitalia are illustrated by the Lepidoptera Dissection Group.
