The Spine-tufted skimmer, or brown-backed red marsh hawk, (Orthetrum chrysis) is a species of dragonfly in the family Libellulidae. It is widespread in many Asian countries. It is a medium sized dragonfly with dark thorax and blood-red abdomen. It looks very similar to Orthetrum pruinosum in shape and size; but can be distinguished by the color of the abdomen. The abdomen of the female is ochreous brown. It breeds in pools and marshes.

GBIF citizen-science records
It is estimated from how often the Brown-Backed Red Marsh Hawk is recorded against all the insects logged in Sinharaja Forest Reserve (25 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.
