Damselfly exuviae for ID

Here are two from yesterday found in the same place as the dragonfly exuvia.

1 a+b. I think these two are the same type of damselfly and that could just could be a clue .

1a. 1b.


2.

Based on the imago, rather than the exuvia, number 1 is a male Azure Damselfly.
I wouldn't like to say what number 2 is, other than it is a Coenagrionidae species of some sort. The identification of damselfly exuviae is made much easier if the shape, and patterns, of the caudal lamellae can be examined (they can usually be teased apart and straightened if then are moistened first).

I'm not even going to attempt an ID - until I get my copies of Steve Cham's guides to both Dragonfly and Damselfly larvae and exuviae . Both are orderable from the British Dragonfly Society ( they publish them as well ). More books - more fieldwork - less time. It's a hard life.

I have the dragonfly edition on my birthday list, it isn't until October but I like to be prepared .
Mind you if the the Dutch guide by Christophe Brochard is ready then I will opt for that.

There is also a very nice Field Guide to the Micro-Moths of Great Britain and Ireland on the list .
