Common Namepowdered flatwing
FamilyMegapodagrionidae (flatwings)
Genus/SpeciesAustroargiolestes calcaris (Fraser, 1958)
Abundance &
Distribution
Locally common between Melbourne and Canberra and also occurs in the Blue Mountains.
HabitatInhabits rocky streams, pools and boggy seepages from relatively low altitudes (but generally at cold streams) to above the snow line.
Description &
Identification
Mature males are readily identifiable by the thorax (only) being very pruinose. Mature females can also be quite pruinescent on the thorax. These are medium-sized damselflies that perch with their wings spread flat (except shortly after emerging). Their abdomen is almost completely black, except for small pale marks on the side at the front of most segments. The thorax is black with significant white markings on the side (mostly covered by pruinescent when mature).
Similar SpeciesAll flatwings, Austroargiolestes in particular, look very similar and a good view of the lower side of the thorax is required. Although Austroargiolestes icteromelas are considerably larger, females appear very similar to A. calcaris females. Refer to the Theischinger & Endersby Identification Guide to separate them properly.
Behaviour &
Observations
Although males are more abundant around breeding sites, both sexes will mostly be found perched on vegetation beside a stream. Males tend to find sunny rocks emerging from streams to perch on and wait for passing females.
