Orthetrum testaceum, common names Crimson Dropwing or Orange Skimmer is an Asian freshwater dragonfly species belonging to the family Libellulidae. This common species is widespread throughout India, Indonesia, Malaysia, Philippines, Singapore and Thailand. These dragonflies may occur in various areas with standing waters, as in ponds, drains, marshes, around rivers, streams, lakes, and gardens.
Orthetrum testaceum can reach a body length of about 43–48 mm (1.7–1.9 in), with a hindwing of 34–38 mm (1.3–1.5 in) (in males). In these large dragonflies the thorax of adult males is orange-brown, with a vermilion red abdomen. The eyes are light brownish. The wings are smoky transparent, with an amber patch at the base. In adult females and in recently emerged males the body is olive-green to brown in colour with black markings and a clear base of the hindwings.
These dragonflies are rather similar to Orthetrum chrysis, but O. testaceum is more reddish, while O. chrysis has a reddish brown thorax. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Orange Skimmer is recorded against all the insects logged in Kerinci Seblat National Park (7 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.
