In 3 days ~60% in a week ~90%
Nesoxenica leprea, commonly known as the Tasmanian xenica, is a butterfly and the only species from the genus Nesoxenica in the brown family Nymphalidae, subfamily Satyrinae. This species is native to Australia and is the only butterfly genus to be endemic to Tasmania. Its restricted distribution to Tasmanian mountains has led to theories of it being a Gondwanan relict.
As adults, they are quite similar in appearance with both males and females reaching 32–42 mm (1.3–1.7 in) in wingspan. Their wings are relatively narrow with the rounded termen and a very hairy basal area. Upperside: black with either cream or pale-yellow markings, white chequered terminal scale-fringe, cream median band on the fore wing with subapical band being narrower, cream median band on hind wing and two obscure black postmedian dots. Worn specimens tend to have white markings and pale yellow in newly emerged specimens, changing to cream after a few hours. Underside: fore wing is similar to the upperside except has pale yellow markings, with either one or two black obscure subapical dots and numerous white subterminal dots, black ground colour on hind wing with markings of silvery-white, and...

Possible
About 20% of wildlife watchers report a Delicate Xenica sighting in Cradle Mountain-Lake St Clair National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 6th most-seen of the 20 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January and February
In those months about 40% of wildlife watchers report a Delicate Xenica in Cradle Mountain-Lake St Clair National Park on a given day, against under 5% in April to November, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Delicate Xenica sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Cradle Mountain-Lake St Clair National Park, in our data
Cradle Mountain-Lake St Clair National Park is the only park on Wallace's Line with enough records to rate Delicate Xenica sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Nymphalidae
The closest relatives of the Delicate Xenica that you can see in Cradle Mountain-Lake St Clair National Park (family Nymphalidae, Brush-footed Butterflies) are Hobart Brown (about 30%), Shouldered Brown (about 20%) and Yellow Admiral (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Delicate Xenica is recorded against all the insects logged in Cradle Mountain-Lake St Clair National Park (22 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.
