Lilypad damselfly, Ischnura kellicotti. An immature female resting on, you guessed it, a lilypad!
Nearby, a male of the same species resting on yet another lilypad.
The leaves of the spatterdock lily make wonderful resting and hunting places for a variety of insects, frogs, arthropods and even some birds. The flowers of the spatterdock are bright yellow and make a nice contrast with the dark waters of the pond.
