Paracrania chrysolepidella (Zeller, 1851)
[Lepidoptera: Eriocraniidae]

Small Hazel Purple


Micropteryx chrysolepidella Zeller, 1851. Linn. Ent. 5: 342
Eriocrania chrysolepidella
(Zeller, 1851)
Paracrania chrysolepidella
(Zeller, 1851)


Leaf-miner: The larva feeds on hazel or hornbeam, creating blotches with intertwining threads of frass, typical of the genus (UKMoths).

Large white blotch, starting at the leaf margin. Frass in long threads. Often several larvae in a mine. Pupation outside the mine (Bladmineerders van Europa).

The mine is also illustrated in British leafminers.

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).

White with a pale brown head; a pair of brown spots on the pronotum (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 by Rob Edmunds (as Eriocrania chrysolepidella). The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
