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...

With luck
About 10% of wildlife watchers report a Turkestan Cockroach sighting in Rome on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 187th most-seen of the 289 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.
June to August
In those months about 10% of wildlife watchers report a Turkestan Cockroach in Rome on a given day, against under 5% in September to May, the lowest months. Those are among Rome's driest months, with about 30 mm of rain a month against 110 mm in November.
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.
9th of 14
Of the 14 cities where we can rate Turkestan Cockroach sightings, Rome ranks 9th at about 10%. The best odds are in Shymkent (Kazakhstan, about 30%), Tashkent (Uzbekistan, about 30%) and Yerevan (Armenia, about 20%).
GBIF citizen-science records
It is estimated from how often the Turkestan Cockroach is recorded against all the insects logged in Rome (9 verified sightings), 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.
