Eriophyes crataegi
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 crataegi causes galls to form on the leaves of Hawthorn. The galls are usually heaviest around the leaf margins and are visible on both sides of the leaf, but the opening is situated below.
