Orthetrum sabina, the slender skimmer or green marsh hawk, is a species of dragonfly in the family Libellulidae. It is widespread, being found from south-eastern Europe and North Africa to Japan and south to Australia and Micronesia.
It is a medium-sized dragonfly with a wingspan of 60-85mm. Adults are greyish to greenish yellow with black and pale markings and green eyes. Its abdomen is greenish-yellow, marked with black. It is very similar to Orthetrum serapia in appearance, with both species appearing in northern Australia. Pale markings on segment four of the abdomen do not extend into the posterior section when viewed from above on Orthetrum sabina. Females are similar to males in shape, colour and size; differing only in sexual characteristics. This dragonfly perches motionless on shrubs and dry twigs for long periods. It preys voraciously on smaller butterflies and dragonflies.
The genus name Orthetrum is derived from the Greek ὀρθός (orthos, "straight") and ἦτρον (ētron, "abdomen"), referring to the parallel-sided abdomen of the genus. The species name sabina is possibly named for Saint Sabina.

Possible
About 20% of wildlife watchers report a Slender Skimmer sighting in Vasai-Virar on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 17th most-seen of the 20 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 80%, if each day is a fresh chance.
August
In that month about 50% of wildlife watchers report a Slender Skimmer in Vasai-Virar on a given day, against under 5% in February–April, June and September–December, the lowest months. That is one of Vasai-Virar's wettest months, with about 620 mm of rain against almost none in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Slender Skimmer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
33rd of 73
Of the 73 cities where we can rate Slender Skimmer sightings, Vasai-Virar ranks 33rd at about 20%. The best odds are in Yogyakarta (Indonesia, about 60%), Kota (India, about 50%) and Dammam (Saudi Arabia, about 50%).
Same family: Libellulidae
The closest relatives of the Slender Skimmer that you can see in Vasai-Virar (family Libellulidae, Skimmers) are Scarlet Skimmer (about 40%) and Chalky Percher (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Slender Skimmer is recorded against all the insects logged in Vasai-Virar (5 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.
