Incurvaria praelatella (Denis & Schiffermüller, 1775)
[Lepidoptera: Incurvariidae]

Strawberry Bright


Tinea praelatella Denis and Schiffermüller, 1775. Wien. Verz.: 320.
Incurvaria praelatella
(Denis and Schiffermüller, 1775).


Small (less than 1 cm), full depth blotch, transparent when fresh, starting at the leaf margin, usually near the leaf tip; frass in scattered grains. The larva makes an elliptic double sided excision to form a case. Subsequently, it continues feeding within the case (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 male genitalia, but not the female genitalia (check for update), are not illustrated by the Lepidoptera Dissection Group (check for update).
