Zyxomma petiolatum, known by the common names long-tailed duskdarter, brown dusk hawk and dingy duskflyer, is a species of dragonfly in the family Libellulidae. It is widespread in many Asian countries, New Guinea, northern Australia and islands in the Pacific.
It is a medium-sized chocolate-brown colored dragonfly with emerald-green eyes. Female is similar to the males. It breeds in small pools, ponds, swamps and slow flowing rivers. It is crepuscular but may also be active during overcast days. Usually seen in the evening as an extremely rapid flyer, flying low over water-bodies, hawking midges and mosquitoes. In daytime it roosts among vegetation and can be difficult to find.
The genus name Zyxomma is derived from the Greek ζεῦξις (zeuxis, "yoking" or "joining together") and ὄμμα (omma, "eye"), referring to the large, adjoining eyes. The species name petiolatum is derived from the Latin petiolus ("small foot" or "leaf stalk"), referring to the excessively slender part of the abdomen.

GBIF citizen-science records
It is estimated from how often the Dingy Dusk-Darter is recorded against all the insects logged in Kaohsiung (7 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.
