Two types of damselfly, Compton Park pool

Large red damselfly and a common blue damselfly, both seen resting on bulrush leaves at the edge of Compton park pool on the same day. Both insects are males.

When I saw them, there were perhaps half a dozen of the blues flying around, but just the one red pictured here.
