Lime nail gall mites are microscopic animals (less than 0.2mm long) that feed on the foliage of lime trees (Tilia sp). The mites feed by sucking sap. They secrete chemicals into the plant tissue that causes the leaves to produce the galls. The mites then suck sap from plant cells lining the gall structure.
Between May and June, upper leaf surfaces of lime trees may develop many pale yellow or red pointed tubular structures up to 5-8mm long. Although the lime nail gall mite disfigures the foliage it has little or no effect on tree growth.
