Using high-speed video recordings, we carried out an analysis of the locomotion gaits of the following aquatic Heteroptera: coral treaders Hermatobatesweddi (Hermatobatidae), sea striders Halovelia septentrionalis (Veliidae), and water striders Metrocoris histrio (Gerridae), in the Island of Amami Oshima, Kagoshima Prefecture, Japan. Most insects use an alternating double tripod gait for walking,...
We measured the force of free pulling water striders, using a hair attached to their backs and a 3D strain gauge force sensor. We showed the repeatability and accuracy of this method. The error of the method was estimated by comparing the projected angles of the force vector on each plane derived from the force data, with those angles derived from video recordings, and was estimated as 12.4%.
