Erythemis simplicicollis, the eastern pondhawk, also known as the common pondhawk, is a dragonfly of the family Libellulidae, native to the eastern two-thirds of the United States and southern Ontario and Quebec, Canada. It is a dragonfly of ponds and still waters. The species is distinguished in that the female is bright green with a banded abdomen and the mature male has a blue abdomen with a green face and green and blue thorax.
Nymphs of the eastern pondhawk are identifiable by their green eyes. When they leave the water and moult for the final time, the emerging immature adult is dull olive green but over the course of a few hours, the abdomen becomes bright green, there is dark brown banding and the heads take on a metallic green sheen. Over the course of their adult lives the green of the male is gradually transformed into a duller shade of blue and finally a powdery bluish-grey. The wings are distinctively veined and have dark margins near the apices. The length of this dragonfly is 36 to 48 mm (1.4 to 1.9 in).
The eastern pondhawk is native to parts of North America and Central America. Its range includes the provinces of Ontario and Quebec... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Eastern Pondhawk is recorded against all the insects logged in Big Cypress National Preserve (95 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.
