Coleophora laricella (Hübner, 1817)
[Lepidoptera: Coleophoridae]

Larch Case-bearer



Tinea laricella
Hübner, 1817. Samml. Europ. Schmett.: 164
Coleophora laricella
(Hübner, 1817).


Leaf-miner and case-bearer: The larvae feed on the needles. When occurring in large numbers, entire trees can be damaged, the needles turning pale as the larvae eat them from within. A number of cases are built as the larvae grow, often in the centre of a floret of needles (UKMoths).

The case is also illustrated in British leafminers and 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).

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

The cremaster is 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: The adults fly in June and July and are attracted to light (UKMoths).
