Eriophyes exilis

Alternative names
Aceria exilis
Description

Eriophyes exilis is a mite that causes galls to form on the leaves of Lime. The galls are seen more frequently than the mite. The gall is a hairy hemispherical bump raised 2 or 3 mm on the top surface of the leaf, and follows the main veins. Below there is a small hairy swelling, but ungalled leaves also have hairs in the axils on the underside of the leaf, so it is essential to make surethat there is a visible swelling on the top surface. Hairs are white, later brown.
