Emerald Damselflies at Rainham Marshes - coming soon?

I don't really know why, but I've not found any Lestes damselflies, the Emeralds, at Rainham Marshes in the last couple of years - despite looking for them.

Rainham Marshes has been known for both Lestes sponsa (the common Emerald Damselfly) and the much rarer Lestes dryas, Scarce Emerald Damselfly, which can be found in well-vegetated ditches and pools at sites along the Thames estuary.

We're not yet in the main season for either species, but I've been very pleased in the last couple of weeks to find a total of 4 individuals of Lestes sponsa - a male and 3 females. I've not found any dryas yet, but I'm still looking!

Here's a female Emerald Damselfly (Lestes sponsa) from yesterday (8th July 2014)
