Description
Studies into the occurrence of H. longicaudata have shown the widespread presence of this species, in addition to H. punctata, in all Districts of the County of Rostock. About 66 % of all grassland sites investigated were found to be infested. The degree of infestation increased along with the cultivation of excellent host plants as well as along with rising pH values. Both species were recordable also from arable land with high cropping concentrations of forage grasses and cereals. In the latter case, however, only 16 % of all fields investigated were infested, most of them to minor degrees.
