2013 (CHF):This is the commonest of the three Elm-feeding Stigmella species and is widespread wherever elm grows in the county. The mine often follows the leaf margin (hence the old name of marginicolella. The first section of the mine is almost entirely filled with frass. Frass in the later mine is often coiled. The larva is yellow and the exit slit is always on the upper surface of the leaf. In Stigmella ulmivora the early gallery contains linear frass, the larva is green and the exit is on the underside. Mines at times can be reminiscent of Stigmella viscerella but in these cases the early mine forms a coil rather than the typical "intestine-like" loops of viscerella
