| description | Halovelia septentrionalis Esaki is one of the endangered marine water striders found along the Japanese coast. It is of primary importance to investigate its life history in the field so as to develop conservation measures as well as to understand how this species has adapted to marine environments. We studied its life history in Misaki on the southern part of the Miura Peninsular near Tokyo, ca. 35°N, probably the northernmost locality not only for H. septentrionalis but also for any Halovelia species, most of which are found in warm tropical or subtropical waters. The southern part of the Miura Peninsular has jagged coastlines with deep inner bays. Adults and nymphs were found skating along the rocky shore of inner bays with overhanging vegetation nearby. This species appeared to have at least 2 generations a year and to overwinter in the adult stage. We discussed its overwintering strategy in comparison to those of two other Japanese marine water striders. |
