Periplaneta lateralis (also Shelfordella lateralis, Blatta lateralis), commonly known as the Turkestan cockroach, red runner cockroach, or rusty red cockroach, is a primarily outdoor-dwelling cockroach native to an area stretching from northern Africa to Central Asia.
The species is found in Central Asia, the Caucasus Mountains, and northeastern Africa. It can be found throughout the area of Afghanistan, Azerbaijan, Egypt, India, Iran, Iraq, Israel, Jordan, Kashmir, Libya, Palestine, Pakistan, Saudi Arabia, Sudan, the United Arab Emirates, Russia (adventive) and the United States (adventive).
The Turkestan cockroach was first noticed in the US in 1978, around the former Sharpe Army Depot in California, followed shortly after by appearances at Fort Bliss in Texas and several other military bases. Researchers believe the species arrived on military equipment returning from Central Asia, perhaps Afghanistan. Since then the species has been rapidly replacing the common oriental cockroach (Blatta orientalis) in urban areas of the Southwestern United States “as the most important peri-domestic species”, with advantages of laying more eggs and maturing...

No species of the same family or order lives in Zion National Park, so these are its closest relatives here: other insects.
Possible
About 20% of wildlife watchers report a Turkestan Cockroach sighting in Zion National Park on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 114 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report a Turkestan Cockroach in Zion National Park on a given day, against under 5% in October to February, the lowest months. That is one of Zion National Park's driest months, with almost no rain against 75 mm in March.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Turkestan Cockroach sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 3 parks where we can rate Turkestan Cockroach sightings, Zion National Park has the highest daily chance: about 20%. Next come Joshua Tree National Park (United States, about 10%) and Saguaro National Park (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Turkestan Cockroach is recorded against all the insects logged in Zion National Park (29 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.
