With luck
About 10% of wildlife watchers report a Comstock's Bromeliad Fly sighting in Joshua Tree National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 117th most-seen of the 190 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.
February to May
In those months about 10% of wildlife watchers report a Comstock's Bromeliad Fly in Joshua Tree National Park on a given day, against under 5% in June to January, the lowest months.

GBIF citizen-science records
It is estimated from how often the Comstock's Bromeliad Fly is recorded against all the insects logged in Joshua Tree National Park (10 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.
