Arhopala birmana
In 3 days ~40% in a week ~70%
Arhopala birmana, the Burmese bushblue, is a species of lycaenid or blue butterfly found in the Indomalayan realm. The easternmost form of this species: corthata Fruhst. flying in Hongkong is presumably very closely allied to ariel. In corthata the upper surface of the male is dark, but intensely bluish-violet. Easily separable from typical birmana by the hindwing in which the dark marginal band is analwards narrower. -
In typical birmana Mr. (= arisba Nic.) the postmedian band on the forewing beneath is still coherent, whereas in the larger form aberrans Nic. [ now species Arhopala aberrans (de Nicéville, [1889]) ] it is interrupted in the centre. In this form from Tenasserim the female has also much more white in the disc of the forewing above. The male of all the forms are above violettish-blue with a broader or narrower black margin. Wikipedia →

Possible
About 20% of wildlife watchers report a Burmese Bushblue sighting in Taroko National Park on a given day, based on 26 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 87th most-seen of the 447 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July and September
In those months about 30% of wildlife watchers report a Burmese Bushblue in Taroko National Park on a given day, against under 5% in February–March, May and October–December, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Burmese Bushblue sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Taroko National Park, in our data
Taroko National Park is the only park on Wallace's Line with enough records to rate Burmese Bushblue sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Burmese Bushblue is recorded against all the insects logged in Taroko National Park (26 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.
