Distribution and habitat

It is distributed almost throughout Europe , in central Russia , in the Caucasus , in Turkey , Iran , Uzbekistan , Mongolia , China, and Japan [3] .

They live on loamy and loessal soil, overgrown with grassy plants or completely free of vegetation. Often found in urban areas [3] .

Imago Description

The body length of adult insects is 4.5-5.5 mm [4] .

Description of the preimaginal stages

Egg

The egg (length 0.90-1.04 mm, width 0.58–0.66 mm) is milky white, oval [3] . From 35th over the entire surface, well visible and longitudinal ribs, about 12 of which are located at the rear pole. At the posterior end of the egg there is an extended process. The length of the egg exceeds the length of the process 2.8–5.6 times [3] .

Larva

First Age

The length of the body is 6.10–7.10 mm [3] . Body elongated; the abdomen is slightly widened to the fifth segment, and then tapers slightly to the tip of the body [3] . Head brown, mandibles dark brown, antennae , maxillae and labium yellowish, pronotum yellowish-brown, medium and zadnegrudka yellowish-gray legs light yellowish brown with brown tarsungulusom (joint tarsal segments and claws), abdominal tergites gray-white, the body and urogomphs are off -white [3] . Macro and micro bristles of the head, chest, some bristles of the abdominal segments are simple; many setae of abdominal segments and urogomfs branchy and worn at apex [3] .

Second Age

The body length is 3.87–5.65 mm [3] .

Third Age

The length of the body is 2.80– 4.50 mm [3] . The head is yellowish brown, the front part of the head and mandibles are light brown, the tergites of the anterior, middle and subardothorae are slightly darkened, the antennae and legs are bright brown, the abdominal slarries are colorless, the setae are brown, the body and urogomphs are off-white [3] .

Pupa

The body length of the pupa is 3.4-3.8 mm [3] . Immediately after pupation, the body is yellow, then it turns orange with a dark edging, the protrusions on the pronotum and abdomen are bright brown; before transformation, the pupa is black, with the exception of the orange pronotum [3] .

Development

The larvae fully develop, from the moment they emerge from the egg until readiness for pupation, after three ages [3] . Larvae of the last age arrange an oval shaped pupa in the soil, 5 mm long [3] .
