Family Gerridae - Water Strider

This page contains pictures and information about Water Strider in family Gerridae that we found in the Brisbane area, Queensland, Australia.
Bugs in family Gerridae are true water striders. They have four long legs with fore legs distinctly shorter. They skate rapidly on the surface of water. They may be winged or wingless. They are found usually in large aggregations in lakes, temporary pools or the quiet parts of creeks. They are predaceous. It is believed that they communicate and sense information by the ripple on water surface.
