Life Cycle Guide
Description
Wingspan: 38-42mm
Worldwide Distribution: Europe to Caucasus
UK Distribution: Well distributed/fairly frequent in England and Wales : Northern England/Scotland-local : Channel Isles-Jersey-local/occasional
UK Conservation Status -
Habitat: Woods : Gardens : Parkland
Similar Species -
Pupa: Pupates among spun leaves
Overwinters as: Ovum
Observations: The antemedian cross-line on the August Thorn E.quercinaria Hufnagel, 1767 turns at a sharp angle back to the basal area just before it reaches the costa.
The postmedian cross-line for the similar species also kinks just before the costa whereas the September Thorn cross-line is a smooth line to the costa.
There is a steady convergence of the cross-lines from the costa to the dorsum.
The moth is attracted to light and is a regular visitor to the light trap where it can appear in good numbers.
