Azure Damselfly exuvia
On 15th May I found the first Azure Damselfly exuvia on emergent vegetation, compared to 1st June last year (17 days earlier). The first Large Red Damselfly exuvia was found 13 days earlier than 2019. Most damselfly larvae can be identified by their tail lamellae - dark veining in this case.
There were lots of damselflies of various species beside the Ock and Sandford Brook yesterday.
