In 3 days ~10% in a week ~20%
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...

Rare
Under 5% of wildlife watchers report a Common Lascar sighting in Singapore on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 484th most-seen of the 1045 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.
February
In that month about 10% of wildlife watchers report a Common Lascar in Singapore on a given day, against under 5% in March to January, the lowest months. That is one of Singapore's driest months, with about 100 mm of rain against 300 mm in December.
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.
6th of 7
Of the 7 cities where we can rate Common Lascar sightings, Singapore ranks 6th at under 5%. The best odds are in Guwahati (India, about 10%), Kozhikode (India, about 10%) and Bandung (Indonesia, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Lascar is recorded against all the insects logged in Singapore (28 verified sightings), 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.
