Eotetranychus carpini rife seems to be on vines only in the southern half of France, and in Italy. It is only found on hornbeams and arbors in the north of our territory, without passing through the vine, which would suppose the existence of a race carpini different from the race vitis present on the vine.
 

The mouth apparatus of this mite, in the form of chelicerae, and its body fused into a single mass (Idiosoma) allow it to be classified in the class of Arachnida, infra-class of Acari. This mite, clearly visible on the leaves, protected by a stylophore, with well-developed palps and long curved chelicerae in the shape of a stylet, is part of the Tetranychidae family, grouping together the large mites that are pests of crops, usually called "Spiders".
