Ectropina raychaudhurii is a moth of the Gracillariidae family. It is known from Tamil Nadu, India. The wingspan is 5.3-6.6 mm. The larvae feed on Phyllanthus niruri. They mine the leaves of their host plant. The first instar larva mines the lower layer of spongy parenchyma just above the lower epidermis, and makes a small blotch-mine or sometimes a linear mine along the leaf-vein. In the second instar, the larva broadens the mine into a large blotch, which finally occupies almost the full area between two branching veins. Up to this stage, the mine is flat and seen only on the lower surface of the leaf, the mining part being whitish in colour. In thethird and fourth instars, the larva which has been transformed into tissue-feeding type, feeds on the remaining tissues within the blotch-min
