Orange Underwing
ARCHIEARIS parthenias (Linnaeus, 1761)
Life Cycle Guide
Description
Wingspan: 35-39mm
Worldwide Distribution: Europe : W. Siberia : Sahkalin Island
UK Distribution: Widespread but local over much of England,Wales and Scotland
UK Conservation Status -
Habitat: Rides and edges of Birch Woodland.
Similar Species -
Larva: April-June : The small larva emerge as the Birch bud is starting to open where they feed on the catkins,foraging nocturnally,spending the day in a web of spun leaves.The full grown larva is green with white lateral lines,the lowest line being broader than the rest.
Pupa: They moth pupates in the surface of soft bark.
Overwinters as : Overwinters as a pupa.
Observations: A beautiful moth that is very active in the early spring sunshine flying high up along the rides or edges of Birch trees before settling on the rides to drink from puddles, where they can be disturbed very quickly indeed before flying back into the Birch canopy.
I have found this moth extremely difficult to photograph as their reaction time to shutter release seems as fast as encountered by the Wall butterfly on occasions. Photo 1 was taken at 1/5000 second but the moth was taking flight in the time it took to press the shutter button.
This moth is extremely difficult to distinguish from its similar species which is the Light Orange Underwing,especially if the habitat includes Aspen its larval food plant. The antennae of A.notha males are slightly feathered whereas in A.parthenias the antennae are slightly serrated.Although the two moths can possibly be encountered together A.parthenias does emerge two weeks before A.notha.
Ovum are deposited on twigs and emerge to feed on catkins in April before eating young Birch leaves at night in spun leaves.
