Across all the parks we cover, that three-hour window holds the most Poplar Grey sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
9th of 13

GBIF citizen-science records
It is estimated from how often the Poplar Grey is recorded against all the insects logged in Porto (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.
