Rare
Under 5% of wildlife watchers report a Say's Mantidfly sighting in Washington on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 1121st most-seen of the 1807 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Say's Mantidfly in Washington on a given day, so our monthly data shows no clear season.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Say's Mantidfly sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 8 cities where we can rate Say's Mantidfly sightings, Washington ranks 7th at under 5%, level with the leaders once rounded. The best odds are in Boston (United States, under 5%), Chicago (United States, under 5%) and Austin (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Say's Mantidfly is recorded against all the insects logged in Washington (12 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.
