In 3 days ~10% in a week ~30%
Gynacantha dravida, also known as Indian duskhawker or brown darner, is a species of dragonfly in the family Aeshnidae. It is found in India and Sri Lanka. It is a large dragonfly characterized by its homogeneous colouring of dull browns and greens, by its long and thin anal appendages, and by its crepuscular habits. Its principal food appears to be mosquitoes and microlepidoptera. During the day, it rests in dark thickets. Fully matured specimens have bright colours; blues and greens, developing very late in life. Young specimens have brown color with some dark shades. Females are exactly similar to the males in colors and markings.
It is very closely related to Gynacantha subinterrupta and it is difficult to distinguish them. But the relative lengths of the superior and inferior anal appendages are different. The inferior being more than one-third the length of superiors in G. dravida and less than one-third in G. subinterrupta.

Rare
Under 5% of wildlife watchers report an Indian Duskhawker sighting in Pune on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 293rd most-seen of the 340 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March, July and November–December
In those months about 10% of wildlife watchers report an Indian Duskhawker in Pune on a given day, against under 5% in January–February, April–June and August–October, the lowest months.
6th of 6
Of the 6 cities where we can rate Indian Duskhawker sightings, Pune ranks 6th at under 5%. The best odds are in Kozhikode (India, about 10%), Colombo [Sri Jayawardenepura Kotte] (Sri Lanka, about 10%) and Kochi (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Indian Duskhawker is recorded against all the insects logged in Pune (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.
