| Chris Rombough observed water striders (family Gerridae, aka water skippers, pond skaters, and jesus bugs) walking on the surface of the shallow edge of a pond in Deschutes County Oregon. The pond contained clusters of newly-hatched Oregon Spotted Frog, Rana pretiosa, tadpoles, which remained still in clusters on top of the degrading egg masses as frog egg embryos do before they disperse indivitually into the pond as developing tadpoles. In these pictures we see a water strider above the embryos capturing one of them, then two views of the strider as it begins to feed on it. © Chris Rombough | This short video shows the water strider beginning to eat the embryo then moving away from a rival water strider. © Chris Rombough |
