Dusky Thorn
ENNOMOS fuscantaria (Haworth, 1809)
Life Cycle Guide
Description
Wingspan: 38-42mm
Worldwide Distribution: Europe to western Siberia : North Africa
UK Distribution: Well distributed/fairly frequent in England and Wales to Yorkshire : Channel Isles-widespread/occasional
UK Conservation Status -
Flight Period: Mid July to mid October
Habitat: Woods : Gardens : Hedgerows : Where larval food plant grows
Similar Species -
Pupa: Pupates among leaves of food plant
Overwinters as: Ovum
Observations: Although the August Thorn E.quercinaria Hufnagel, 1767 can also have a darker distal area on the forewing like the Dusky Thorn E.fuscantaria Haworth, 1809, the cross-lines for this moth are further apart at the dorsum.The postmedian fascia of this moth has a smooth and gentle curve at the costa, unlike its similar species where the line kinks at the same point.
The moth is attracted to light and is often seen at the moth trap or within the vicinity on a wall or fence.
