Rare
Under 5% of wildlife watchers report a Chalepus walshii sighting in Denver on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 352nd most-seen of the 461 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 Chalepus walshii in Denver on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Chalepus walshii sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Denver, in our data

GBIF citizen-science records
It is estimated from how often the Chalepus walshii is recorded against all the insects logged in Denver (7 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.
