Coleotechnites piceaella (Kearfott, 1903)
[Lepidoptera: Gelechiidae]

Spruce Groundling


Recurvaria piceaella Kearfott, 1903. Journal N. Y. ent. Soc. 11: 155, t. 9 fig. 10.
Coleotechnites piceaella
(Kearfott, 1903).


Leaf-miner: A group of four to six leaves are completely mined out from the base on. The leaves have a hole near their base; these entrances may be connected by a silken tube. Between the leaves a loose spinning. All frass is ejected. Mines preferably occur when a tree has been weakened by weather conditions or insect pest damage (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).

Orange brown, straw coloured to brick red with light brown head; much darker during the winter rest. Pronotum darker, with lighter anterior border (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 not illustrated in UKMoths (check for update). The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).
