With luck
About 10% of wildlife watchers report a Pseudomasaris vespoides sighting in Yosemite National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 134th most-seen of the 227 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Pseudomasaris vespoides is recorded against all the insects logged in Yosemite National Park (9 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.
