 Patterns Created by a Water Strider

   Summary Authors:  Bertrand Kulik;  Jim Foster

   The curious wave pattern featured above was made on a small stream by a
    water strider, at center. The contrast between light and dark is so
   strong here because the photo was snapped in bright sunlight. Thanks to
    surface tension, a strider’s (also known as water spiders, or pond
   skaters) long, thin legs and micro hairs, over its entire body, enable
   it to “ walk” over the water’s surface. Note that where its legs
   touch the water, minute depressions are formed on the surface that act
   as miniature mirrors.
