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 Springbrook National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 91st most-seen of the 429 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.

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.
2nd of 3
Of the 3 parks where we can rate Orange Threadtail sightings, Springbrook National Park ranks 2nd at about 10%. The best odds are in Lamington National Park (Australia, about 30%).

GBIF citizen-science records
It is estimated from how often the Orange Threadtail is recorded against all the insects logged in Springbrook National Park (19 verified sightings from 2019 to 2026), 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.
