Gadira sp. ‘black brown EGW’ (of Stringer et al. 2012)
Current DoC threat status
Naturally Uncommon
Recognition / similar species
None. The chocolate brown forewing colour combined with its small size make it distinctive.
Known distribution and abundance
Small dry rocky area west of Lake Benmore from 660-920m. One site is on the Black Forest Transmission Road at Scrub Gully where just one individual was trapped at light on 24 February 2001. This adult came to the light immediately the light was turned on; maybe indicating it is dusk-active or diurnal species.
Habitat
Steep dry rock faces dominate the known habitat.
Host-plant and biology of early stages
Not known, but the rock face habitat where it has been found contains lichens and mosses, which based on related species may be the hostplant of the larvae.
Flight period (months of year) and behaviour of adult
All four known adults have been found in February.
Potential monitoring technique(s)
Given the paucity of adults known, until more is known about the species’ biology and its larval hostplant it will be uneconomic to monitor the adult moth.
Threats
If it inhabits the dry and steep rockfaces then it is probably does not have any current threats. Never-the-less security of this habitat is desirable to ensure the long-term viability of the species.
