Cryptocercus punctulatus, known generally as brown-hooded cockroach, is a species of cockroach in the family Cryptocercidae. Other common names include the woodroach, wingless wood roach, and eastern wood-eating cockroach. It is found in North America.
C. punctulatus are distributed within the eastern United States of America, concentrated within the Appalachian Mountains of western Virginia and Pennsylvania. They share this habitat with three other closely related congeneric species, C. darwini, C. garciai, and C. wrighti, although no sympatry has been documented among the species. They inhabit temperate forests within the Appalachian Mountain Range and Allegheny Mountains in either deciduous forests or forests mixed with both deciduous and coniferous trees. They are predominantly found in elevations greater than 400 meters above sea level. C. punctulatus can be found in western Virginia, West Virginia, and Pennsylvania. They do not inhabit logs where the other species are found. Research has shown that C. punctulatus has diverged from C. darwini, C. garciai, and C. wrighti 13 to 38 million years ago. Because these are wingless cockroaches their distribution... Wikipedia →

No species of the same family or order lives in Shenandoah National Park, so these are its closest relatives here: other insects.
Rare
Under 5% of wildlife watchers report a Brown-Hooded Cockroach sighting in Shenandoah National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 630th most-seen of the 723 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Brown-Hooded Cockroach in Shenandoah National Park on a given day, against under 5% in October to June, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Brown-Hooded Cockroach sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Shenandoah National Park, in our data
Shenandoah National Park is the only park on Wallace's Line with enough records to rate Brown-Hooded 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 Brown-Hooded Cockroach is recorded against all the insects logged in Shenandoah National Park (7 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.
