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 →

Rare
Under 5% of wildlife watchers report an Orange Threadtail sighting in Blue Mountains National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 681st most-seen of the 789 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
December
In that month about 10% of wildlife watchers report an Orange Threadtail in Blue Mountains National Park on a given day, against under 5% in January 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.
3rd of 3
Of the 3 parks where we can rate Orange Threadtail sightings, Blue Mountains National Park ranks 3rd at under 5%. The best odds are in Lamington National Park (Australia, about 30%) and Springbrook National Park (Australia, about 10%).
Same order: Odonata
The closest relatives of the Orange Threadtail that you can see in Blue Mountains National Park (order Odonata, Dragonflies and Damselflies) are Sydney Mountain Darner (about 20%), Common Flatwing (about 20%) and Eastern Evening Darner (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Orange Threadtail is recorded against all the insects logged in Blue Mountains National Park (5 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.
