Agonopterix propinquella (Treitschke, 1835)
[Lepidoptera: Depressariidae]

Black-spot Flat-body


Haemylis propinquella Treitschke, 1835. Schmett. Europ. 10 (3): 184, 280
Agonopterix propinquella (Treitschke, 1835).


 

Leaf-miner: The eggs of this species are laid on a leaf, with the larvae mining the underside of the leaf, until a late instar when it feeds in a web under the midrib of the leaf, causing visible blotching on the upperside (UKMoths).

Short, full depth corridor. The larva relatively long lives as a miner, but finally leaves the mine and continues living in spinning along the midrib at the leaf underside, from where windows are eaten in the leaf (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).

Larva with black head and prothoracic shield. Body, thoracic feet and anal shield apple green; pinacula grey (Bladmineerders van Europa). The larva is also illustrated in UKMoths.

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

The larva pupates in August, usually amongst the leaf litter, occasionally within the web. The pupa is illustrated in UKMoths.

Adult: The adult is illustrated in UKMoths. The male genitalia, but not the female genitalia (check for update), are illustrated by the Lepidoptera Dissection Group.
