Life History of an Endangered Marine Insect Halovelia septentrionalis Esaki (Hemiptera: Veliidae)

open access: yesPsyche: A Journal of Entomology, Volume 2015, Issue 1, 2015., 2015
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
