Orange Alert!

The fine weather, which has persisted since May 20th, means that 'early' emerging sites in the Southeast can now be placed on Orange Alert - that's Bookham Commons, Knepp Wildland and sites in and around the M25 perambulation. 

The weather during the pupation and pupal development periods has been remarkably clement, and we know that weather during that whole period plays a key role in determining adult numbers.

Please note that first sightings of the year have to be 100% definite to get accepted (I was the victim of this rule myself this time last year, when I discounted a fleeting glimpse only to find a male on territory in the same spot the following day).
