Under 5% of wildlife watchers report a Dark Wood Cockroach sighting in Everglades National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 439th most-seen of the 496 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.
May, August–September and December
In those months about 10% of wildlife watchers report a Dark Wood Cockroach in Everglades National Park on a given day, against under 5% in January–April, June–July and October–November, the lowest months.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Dark Wood Cockroach sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Everglades National Park, in our data
Everglades National Park is the only park on Wallace's Line with enough records to rate Dark Wood Cockroach sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dark Wood Cockroach is recorded against all the insects logged in Everglades National 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.
