gall

the mites live in the length grooves of the grass leaves; on grasses with smooth leaves they are much less numerous. At high densities rolling and withering of the leaves does occur, also growth disturbance, malformations and discolouration of the inflorescence.

synonyms

Eriophyes tenuis.

note

galls like those illustrated above are traditionally attributed to Aceria tenuis in the cecidological literature. However, there are a number of gall mite species more that live on grasses that at high densities probably may cause developmental disturbances.

inquilines

? Aceria cornuta, Aculodes dubius.
