Eublaberus distanti, known as the Six-spotted cockroach, Four-spotted cockroach, Four-spot cockroach, or Trinidad bat-cave cockroach, is a primarily cave-dwelling Central and South American cockroach of the genus Eublaberus (Hebard, 1920) and named after William Lucas Distant.
Nymphs turn a dark brown, and the common name "six spotted cockroach" refers to six yellow spots along the sides of the nymph. Adults of both genders have wings but do not fly. They grow to approximately 6.4 cm (2.5 in) in length. Males are generally smaller than females, with longer wings, and a small rear sternite compared to females.
E. distanti are found in Trinidad and Tobago, Guatemala, Costa Rica, Panama, Colombia, French Guiana, Suriname, Guyana, Brazil, and Peru. E. distanti in Trinidad were observed to prefer relatively dry guano-rich areas in caves, but are occasionally found in rotting logs, under decaying litter, in epiphytes, and in "the rot holes and hollows of trees, particularly those that house bats." Nymphs burrow in organically rich soil on cave floors until their 6th or 7th instar, then climb onto rocky, often guano-covered walls. Caves with guano support typically... Wikipedia →

With luck
About 10% of wildlife watchers report a Trinidad Bat-Cave Roach sighting in Yasuní National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 203 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
November
In that month about 30% of wildlife watchers report a Trinidad Bat-Cave Roach in Yasuní National Park on a given day, against under 5% in April–May and December–January, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Trinidad Bat-Cave Roach 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.
Only Yasuní National Park, in our data
Yasuní National Park is the only park on Wallace's Line with enough records to rate Trinidad Bat-Cave Roach sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Trinidad Bat-Cave Roach is recorded against all the insects logged in Yasuní National Park (12 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.
