Ghost Moth
Encyclopedia
The Ghost Moth also known as the Ghost Swift, is a moth
of the family Hepialidae
. It is common throughout Europe
except for the far south-east. This species is now considered the only species in the genus Hepialus which previously included several other species now reclassified into other genera.
The male has a wingspan
of about 44 mm and both forewings and hindwings are pure white (although in H. h. thulensis, found in Shetland and the Faroe Islands
, there are buff-coloured individuals). The female is larger (wingspan about 48 mm) and has yellowish-buff forewings with darker linear markings and brown hindwings. The adults fly from June to August and are attracted to light. The species overwinters as a larva
.
The Ghost Moth gets its name from the display flight of the male, which hovers, sometimes slowly rising and falling, over open ground to attract females. In a suitable location several males may display together in a lek.
The larva is whitish and maggot
-like and feeds underground on the root
s of a variety of wild and cultivated plants (see list below). The species can be an economically significant pest in forest nurseries
.
The term ghost moth is sometimes used as a general term for all Hepialids.
