Query: Unsteady wave pattern generation by water striders   We perform an experimental and theoretical study of the wave pattern
generated by the leg strokes of water striders during a propulsion cycle. Using
the synthetic Schlieren method, we are able to measure the dynamic response of
the free surface accurately. In order to match experimental conditions, we
extend B\"uhler's theory of impulsive forcing (\cite{buhler}) to finite depth.
We demonstrate the improved ability of this approach to reproduce the
experimental findings, once the observed continuous forcing and hence non-zero
temporal and spatial extent of the leg strokes is also taken into account.
