The orange threadtail or ochre threadtail (Nososticta solida) is an Australian damselfly in the family Platycnemididae. They are medium-sized with a length of around 35mm. Orange threadtails can be found near semi-shaded running water, and usually rest on plants at the water's edge. Orange threadtails may be seen all year round. In Victoria they occur at lower altitudes during summer, though further north they can be seen in spring and autumn. When at rest, Nososticta damselflies hold their wings closely folded up vertically over their thorax. The male threadtails have an orange-yellow thorax with black patterns. Their abdomen is narrow, black in colour with yellow strips. There is a brown yellow colour at the base of their wings. Females are the same size as the males. They are pale brown in colour and have the same black patterns as the males.
Orange threadtails are found in eastern Australian States: Queensland, New South Wales, Australian Capital Territory and Victoria. The genus name Nososticta combines the Greek νόσος (nosos, "disease") with στικτός (stiktos, "spotted" or "marked"). The suffix -sticta is commonly used in names of taxa related... Wikipedia →

With luck
About 10% of wildlife watchers report an Orange Threadtail sighting in Melbourne on a given day, based on 127 verified sightings from GBIF citizen-science data. It is the 143rd most-seen of the 875 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
December to February
In those months about 10% of wildlife watchers report an Orange Threadtail in Melbourne on a given day, against under 5% in March to November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Orange Threadtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Orange Threadtail is recorded against all the insects logged in Melbourne (127 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
