Abstract
Description of structures of the larvae of Hydroporus ferrugineus Stephens and H. polaris Fall is provided including detailed chaetotaxal and porotaxa l analyses. Larvae of H. ferrugineus are distinguished from all other speci es of Hydroporus Clairville by the presence of 1-2 secondary setae on urogo mphomere 1. Larvae of H. polaris are distinguished from all other Nearctic counterparts by the absence of lateral spinulae on the prementum and more e longate urogomphi.
