Eriophyes leiosoma


Gall mites are extremely tiny plant feeders, often around 0.5mm in size. They are members of the Arachnid group, which includes spiders and mites, and are small enough to pierce and feed on individual plant cells, causing the surrounding cells to enlarge and multiply to form the gall. The mite Eriophyes leiosoma has a brown-pinkish appearance and causes a gall which takes the form of hairy patches on the underside of the leaves of lime trees, but additionally causes hairy deformations on the sepals and other flowering parts. The edges of the sepals curl to both sides along the length direction, first covered with white and later with brown hairs.
