About 30% of wildlife watchers report a Hercules Skimmer sighting in Brownsberg Nature Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 51st most-seen of the 74 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

In that month about 50% of wildlife watchers report a Hercules Skimmer in Brownsberg Nature Park on a given day, against under 5% in December to April, the lowest months. September has too few records to rate.

GBIF citizen-science records
It is estimated from how often the Hercules Skimmer is recorded against all the insects logged in Brownsberg Nature Park (5 verified sightings from 2019 to 2026), 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.
