Abstract: In a garden pond i n London, tadpoles of the common frog, Rana temporaria, displayed a clear diel pattern of movement and aggregation. During the morning, tadpoles moved from the deeper area in the middle of the pond to the pond edges. The number of tadpoles around the edges peaked i n the afternoon. At night tadpoles tended to disperse and move back to t h e deeper area. This cycle was closely related to t h e diel cycles of illumination and temperature. Tadpoles were not evenly distributed around the pond edges, and a stationary feeding aggregation was formed each day on the west to south-west edge. As there was no thermal gradients along the pond edges, the formation of this aggregation was probably d u e to factors other than temperature.
