It is widespread in Europe , Russia , the Caucasus , Central Asia , Turkey , Georgia , Kazakhstan , Mongolia and on the island of Hokkaido in Japan [3] , where it is found at altitudes from 500 to 2100 meters above sea level [5] .

The body length of adults is 8–10.5 mm [4] . Elytra elytra black. On the pronotum there is a very narrow reddish lateral border, which is often almost imperceptible [4] .
Larvae of this species differ from other species of their genus, in particular from the nearest Harpalus rufipes , in the following characters [6] :
- the width of the head is one and a half times its length; the widest point is behind the eyes;
- cervical impressions long and elongated forward;
- keels protrude back apart above both eyes ;
- on the second segment of each antennal flagellum there are two setae, on the first there are no setae;
- mandibles (mandibles) are as elongated outward as Harpalus rufipes , but only having only two denticles on apex inside the curved retinaculum ;
- cerci are almost twice as long as anal tubes.
Larvae that have just hatched from eggs have four large fangs [6] .
It is inhabited by forests , forest-steppes , meadows , forest glades, city parks [7] [8] [9] [10] [11] . Prefer sandy soils [12] . Adult beetles of this species, like Pterostichus and some staphylinids , are able to detect pupae of moths in fruits , such as apples , and pull them out of there [13] . Larvae are active everywhere in their range all year round, but most of them are found in winter [6] .
