Omocestus haemorrhoidalis: Male (eastern Swabian Alb) [N] Omocestus haemorrhoidalis: Female (eastern Swabian Alb) [N] Omocestus haemorrhoidalis: Female (eastern Swabian Alb) [N] Omocestus haemorrhoidalis: Female, green form (eastern Swabian Alb) [N] Omocestus haemorrhoidalis: Habitat-detail: typical are moss- and lichen-rich, but otherwise scarcely vegetated places [N] Omocestus haemorrhoidalis: Habitat on the Swabian Alb [N]

Nutrition:
Grasses

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.
