Carabus scabrosus, common name huge violet ground beetle, is a species of beetle of the family Carabidae. Carabus scabrosus can reach about 50 millimetres (2.0 in) in length and about 30 millimetres (1.2 in) in width in the broadest part of elytra. This is among the largest of the known Carabus beetles. The basic colour varies from bluish-black to violet or dark reddish brown. Black varieties of the beetle typically also show a high absorption in the near-infrared part of the spectrum.
The thorax is broad, truncated anteriorly and posteriorly, very slightly convex. The elytrtra are oval, convex, and covered throughout with small tubercles. Also, the pronotum has a rugose, granular surface. Biolib Fauna europaea

Possible
About 20% of wildlife watchers report a Carabus scabrosus sighting in Istanbul on a given day, based on 58 verified sightings from GBIF citizen-science data. It is the 24th most-seen of the 266 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.
September and October
In those months about 30% of wildlife watchers report a Carabus scabrosus in Istanbul on a given day, against under 5% in December to February, the lowest months.
Only Istanbul, in our data
Istanbul is the only city on Wallace's Line with enough records to rate Carabus scabrosus sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Carabus scabrosus is recorded against all the insects logged in Istanbul (58 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.
