Agonopterix heracliana

Alternative names
Common Brindled Brown
Common Flat-body
Description

Wingspan 15 to 21 mm. Identification can be difficult but Agonopterix heracliana can generally be confirmed by checking the hindwing cilia lines, usually showing just one distinct line (with other faint lines possible). However dissection to confirm is preferred.

A. heracliana can be reliably recorded in the larval stage, with the larva showing a green-tinged yellow/orange head.

Where these checks have not been carried out records should be added to the Agonopterix heracliana agg. page.
