Omocestus haemorrhoidalis (Charpentier, 1825)

Habitat:
Omocestus haemorrhoidalis inhabits gappy, shallow and mostly grazed nutrient-poor grasslands in the lower elevations and semi-high mountains. In the Southern Alps it raises to over 2500m above sea level, but occurs in the north only at lower altitudes.

Life cycle:
Adults occur from July to October. The eggs overwinter in the soil or moss.

Endangerment: strongly endangered

Endangerment factors:
Omocestus haemorrhoidalis is severely threatened by the decline in nutrient-poor and especially low growing, gappy grasslands by eutrophication, abandonment of grazing, afforestation, succession, overbuilding and fragmentation.

Remarks:
Omocestus haemorrhoidalis occurs from Southern and Central Europe to Korea.
