The larva has a dark, elongated and segmented body. It can measure a little more than 8 cm. It has three pairs of legs, lateral tectile filaments, tracheal gills and, at the pip of the abdomen, a pair of prolegs. Each of these prolegs has a pair of terminal hooks that allow it to anchor itself in swft currents. The larvae live near the bottom, under rocks or attached to stones and other supports.
