Euspilapteryx auroguttella Stephens, 1835
[Lepidoptera: Gracillariidae]

Gold-dot Slender


Euspilapteryx auroguttella Stephens, 1835. Ill. Brit. Ent. Haust. 4: 363
Eucalybites auroguttella (Stephens, 1835).


Leaf-miner: Larva initially feeding in a gallery which turns to a blotch and finally one or more conical folds are made (UKMoths).

The mine begins as an, occasionally quite long, lower-surface epidermal corridor. Its last section is widened into a blotch. Only then the larva begins to consume parenchymatous tissue and to line the inside of the mine with silk. The upper surface of the mine turns orange brown, and the leaf folds itself around the mine. Frass in a clump in a corner of the mine. In the end the larva leaves its mine, and then lives free in a leaf tip that has been folded downwards (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 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. The genitalia are not illustrated by the Lepidoptera Dissection Group (check for update).

Time of year - larvae: June; September-October (British leafminers).

Time of year - adults: There are two generations, moths being on the wing in May and August. The flight time is evening onwards, and sometimes it can be attracted to light (UKMoths).
