Abacarus hystrix (Nalepa, 1896)

the mites live between the length ridges on the upperside of the leaves. The leaves turn pale greyish green, and are incompletely unfolded.

during the last 50 years the number of described gall-mites has considerably increased, and this applies in particular for grass-inhabitants. Many are not symptomatic, therefore not treated in this website. Even more than for other groups of plants one should realise that for grasses the combination plant species + symptom is insufficient for a reliable identification.

Moreover, DNA-analysis has demonstrated that “A. hystrix” actually is a complex of a number of species (Skoracka & Dabert, 2010a).
