Water Measurer Hydrometra stagnorum (Linnaeus, 1758)
Looking like a very small black Stick Insect, the Water Measurer is likely to escape attention, as it did us for many years. Able to easily walk on the surface of ponds and other still waters, it hunts insects trapped on, or just under the surface. With an almost mechanical-like gait when walking, movement is slow. This one was photographed on a shallow area of water at the former sand quarry at Market Warsop in April 2013, but we have also recorded it from Warsop Main Pit Top.
