Specimens in nature


An elongated, tentiform mine on the underside of a leaf, sometimes reaching from the main vein till the leaf margin, situated between two secondary veins. The last instar applies so much silk in the mine that it is sometimes contorted into a tube. The frass is concentrated in a corner of the mine. Many times there are several mines on one leaf.
