The 3rd-instar larvae of 8 Fennoscandian species of Hydroporus Clairville (Coleoptera: Dytiscidae), with notes on subgeneric classification
Abstract The 3rd-instar larvae of 8 Fennoscandian species of Hydroporus, including the type species of the 2 subgenera Sternoporus Falkenström and Hydroporidius Guignot, are described based on material from N. Sweden. Larvae were reared from eggs laid in captivity, or collected in the field and iden...
