The oriental cockroach (Blatta orientalis), also known as the waterbug (as they live in damp areas) or black cockroach (as their bodies are mostly dark), is a large species of cockroach, adult males being 18–29 mm (23⁄32–1+5⁄32 in) and adult females being 20–27 mm (25⁄32–1+1⁄16 in). It is dark brown or black in color and has a glossy body. The female has a somewhat different appearance from the male, appearing to be wingless at a casual glance, but is brachypterous, having non-functional wings just below her head. She has a wider body than the male. The male has long wings, which cover three quarters of the abdomen and are brown in color, and has a narrower body. Both of them are flightless. The female oriental cockroach looks somewhat similar to the Florida woods cockroach and may be mistaken for it. Originally endemic to the Crimean Peninsula and the region around the Black Sea and the Caspian Sea, its distribution is now cosmopolitan.
Oriental cockroaches tend to travel somewhat more slowly than other species. Often called "waterbugs" since they prefer dark, moist places, they can generally be found around decaying organic matter, in bushes, under leaf groundcover,... Wikipedia →

No species of the same family or order lives in Ankara, so these are its closest relatives here: other insects.
Likely
About 40% of wildlife watchers report an Oriental Cockroach sighting in Ankara on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 32 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
September
In that month about 60% of wildlife watchers report an Oriental Cockroach in Ankara on a given day, against under 5% in November to February, the lowest months. That is one of Ankara's driest months, with about 20 mm of rain against 50 mm in May.
Yes
Of the 37 cities where we can rate Oriental Cockroach sightings, Ankara has the highest daily chance: about 40%. Next come Sofia (Bulgaria, about 20%) and Yerevan (Armenia, about 20%).
GBIF citizen-science records
It is estimated from how often the Oriental Cockroach is recorded against all the insects logged in Ankara (31 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.
