ResumoTo understand the life history strategies of diving beetles, it is important to obtain information regarding their flight capacities. We estimated the flight capacities of three dytiscid species in Japan using a flight mill. The mean flight distances of Hydaticus bowringii Clark, 1864 Clark, H. (1864), 'Notes on the Genus Hydaticus (Leach), with Descriptions of New Species', Transactions of the Royal Entomological Society of London, 12, 209–222. + pl. XIV.[Crossref] , [Google Scholar], Hydaticus grammicus (Germar, 1827 Germar, E.F. (1827), Fauna Insectorum Europae. XIII. Halae: C.A. Kümmel, 25 pp. + 25 pls. [Google Scholar]), and Rhantus suturalis (MacLeay, 1825 MacLeay, W.S. (1825), Annulosa javanica, or an attempt to illustrate the natural affinities and analogies of the Insects collected in Java by Thomas Horsfield, M.D.F.L. & G.S. and deposited by him in the museum of the honourable East-India Company, Number I, London: Kingsbury, Parbury & Allen.[Crossref] , [Google Scholar]) were 5.16, 1.97, and 0.58 km, respectively. Some individuals flew extremely long distances: 20.01 km in H. bowringii and 12.58 km in H. grammicus. The two representatives of the genus Hydaticus Leach, 1817 overwinter on land, far from water bodies or in the mud near emergent plants on the shore of water bodies; R. suturalis uses various water bodies throughout the year. The differences in overwintering sites may be reflected in the species' flight capacities.
