With luck
About 10% of wildlife watchers report a Withered Mocis sighting in Everglades National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 213th most-seen of the 496 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.
May–July and December–January
In those months about 10% of wildlife watchers report a Withered Mocis in Everglades National Park on a given day, against under 5% in February–April and August–November, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Withered Mocis sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.

GBIF citizen-science records
It is estimated from how often the Withered Mocis is recorded against all the insects logged in Everglades National Park (13 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.
