Pantoporia hordonia, the common lascar, is a species of nymphalid butterfly found in Cambodia, tropical and subtropical Asia. Both male and female have upperside black with orange markings. Forewing: discoidal streak broad, anteriorly twice indented, at apex extending into base of interspace 3; posterior discal spots coalescent, forming an irregular oblique short broad band; anterior spots also coalescent, oblique from costa; a postdiscal obscure grey incurved transverse line, and a very slender, also obscure, orange transverse subterminal line. Hindwing: a subbasal transverse broad band, and a much narrower postdiscal band curved inwards at the ends; beyond this the black terminal margin is traversed by a darker black subterminal line. Underside chestnut-brown, covered with short, slender, transverse brown striae on the margin of the orange markings, which are similar to those on the upperside but broader, paler, and less clearly defined. Forewing: the pale transverse postdiscal and orange subterminal lines of the upperside replaced by a postdiscal lilacine narrow band, defined by somewhat crenulate chestnut-brown lines on each side, and a pale...

Likely
About 40% of wildlife watchers report a Common Lascar sighting in Namdapha National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 39th most-seen of the 71 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
November
In that month about 70% of wildlife watchers report a Common Lascar in Namdapha National Park on a given day, against under 5% in December, the lowest month. That is one of Namdapha National Park's driest months, with about 35 mm of rain against 660 mm in July. June to August have too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Lascar sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Common Lascar sightings, Namdapha National Park has the highest daily chance: about 40%. Next come Taman Negara National Park (Malaysia, about 10%) and Kaeng Krachan National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Lascar is recorded against all the insects logged in Namdapha National Park (8 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.
