In 3 days ~10% in a week ~30%
Pelopidas mathias, the dark small-branded swift, small branded swift, lesser millet skipper or black branded swift, is a butterfly belonging to the family Hesperiidae. It is found throughout much of south, southeast and East Asia, and as far as the Philippines. It is also present in tropical Africa and Arabia.
In 1891, Edward Yerbury Watson described it as: Male. Upperside olive brown: forewing with two small yellowish semi-transparent spots within end of cell, three before the apex, and in the male three oblique discal spots followed by a dark-bordered slender straight impressed glandular streak: hindwing with one or two very indistinct pale discal spots. Female with five discal spots in the forewing, and four or five in the hindwing. Underside paler; markings more distinct; hindwing also with a spot at upper end of the cell. Expanse 1.6 inch. (Moore)
P. mathias is considered a pest to rice-growing cultures, although it is not as damaging to rice plants as Parnara guttata. Newly hatched caterpillars are especially voracious in eating young seedlings. They also use silken threads to roll up and stitch together partially eaten leaves for more... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Small Branded Swift is recorded against all the insects logged in Chennai (6 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.
