3.003 (0018) Map-winged Swift Korscheltellus fusconebulosa (De Geer, 1778)

Resident. Common.
Flight period

Lennon (1863) stated it as uncommon, but had found it on Tinwald Downs (VC72). W. Douglas Robinson (1870-71) had found it abundant in June on Almorness (VC73). Francis Buchanan White of Perth (1895) in his Lepidoptera recorded in Colvend parish (VC73) listed Hepialus valleda and var. gallicus. Gordon (1913) stated it to be "common on roadsides, and often abundant among bracken at or just after sunset, June and July." In 1906 on 6th and 8th June the form gallicus Lederer was taken along with the nominate type.
MOGBI (1983) had only one 10km square post 1960 record and that was for Wigtownshire. Pelham-Clinton (1983) trapped it at Barony College (VC72) on a July 1982 Scottish Entomologists' visit. There are just over 100 records from the Rothamsted data during 1975-93.
With records nearing 500, equally for all three VCs, it is the most frequent species of swift moth, both forms occurring across the region within the same localities.
Form gallicus Lederer, 1853
Over twenty records have been recorded from all three vice-counties.
Life cycle
One generation. Overwinters as a larva, but probably taking two seasons for development.
Larval foodplants
Larvae feed on the roots of Bracken, as well as other herbaceous plants.
The distinctive map-like markings on the forewing are very characteristic.
Wide range of habitats including rough grassland, open woodland and gardens.
Recorders' notes
The Map-winged Swift has no proboscis, so it is never found at sugar or flowers. Records of both sexes and forms required.
