Rare
Under 5% of wildlife watchers report a Cave Bristletail sighting in Washington on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 952nd 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 Cave Bristletail in Washington on a given day, so our monthly data shows no clear season.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Cave Bristletail sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Cave Bristletail sightings, Washington ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Paris (France, under 5%), Boston (United States, under 5%) and New York City (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Cave Bristletail is recorded against all the insects logged in Washington (15 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.
