Where & when was this photo taken, please.
is a junior synonym of the generic name Athetis
There are two lepigone
species under placed Athetis:
Möschler, 1860 (originally placed in the genus Hydrilla
), which is listed in Fauna Sinica Insecta 16, Noctuidae (Chen, 1999), occurs in Henan, Japan and eastern Russia. Its occurrence in Hong Kong would be most unlikely under natural circumstances. It is illustrated on the Moths of Japan website at http://www.jpmoth.org/Noctuidae/Hadeninae/Athetis_lepigone.html.
The second species, lepigone
Roesler, 1877, which is a junior synonym of hospes
Freyer, 1831, is a European species, is even more unlikely to occur in HK naturally. There also appears to be some confusion between the two species in the literature.
Your photo could well be of an Athetis
. Though the moth appears rather worn and the pattern thus indistinct - the highly reflective, shiny scales is typical of the genus, as is the rather flat resting posture. The high reflectivity makes life difficult when photographing moths of this genus using flash photography. I can not make out sufficient detail to confirm your provisional identification, against either the MoJ website photos or the illustration in Fauna Sinica Insecta, which is in black and white (and has very poor detail). There are, however, several other Athetis
species in Hong Kong that, when worn, have a similar appearance to your photo, Athetis bremusa
, A. sincera
, A. hongkongensis
and A. obtusa
Without a specimen, it would not be advisable to try to make an identification to species level based on your photo.
I don't suppose you retained the moth, by any chance?
For now, I think the best that can be said of this moth is that it's likely to belong in the genus Athetis
