Rare
Under 5% of wildlife watchers report a Cave Bristletail sighting in Boston on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 738th most-seen of the 1200 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.
November
In that month about 10% of wildlife watchers report a Cave Bristletail in Boston on a given day, against under 5% in December to October, the lowest months.
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, Boston ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Paris (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Cave Bristletail is recorded against all the insects logged in Boston (14 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.
