Normally I would suggest that you use the National Moth Recording Scheme web-site for moth distribution as they ought to be more up to date than NBN. NMRS does supply updates to NBN, but I think there are currently some "problems" between the two and it may not be happening and past updates may have been removed. Since 2000 the Bucks records are from Ivinghoe Hills area, Grangelands, Calvert and Greatmoor area. The latter two sites are a bit unexpected, but thought to have come as a result of imported soil.
The records from Calvert/Greatmoor/Finemere Wood will, I'm sure, prove to be local dispersal from a colony on the active Calvert landfill site where deep excavations have exposed much calcareous rock and the moth has moved in to exploit the large amount of bird's-foot trefoil now there. That landfill must be one of the most unpleasant areas on earth to run a trap but it might just have to be done...!
I've just been to the maps page on the NMRS site and it says to 'clink inn the link below' to get to them, only problem is that there isn't a link that I can see.
Hi Nigel, my understanding is that until the problems between NMRS and the NBN are sorted the most up-to-date maps available to access are those provided as links from the UK-Moths website (10km resolution).
That's a good record. I don't think there are any nearby records, so a nice addition Nigel.
ReplyDeleteHi Peter, I had a look on the NBN Gateway and the nearest records I could see were Lewknor and, in the other direction, the Aldbury area.
ReplyDeleteAs Peter says, a good record. It fills the gap between Grangelands to the North and Buttler's Hangings to the South
ReplyDeleteSo there are closer populations. Thanks Martin.

DeleteHi Dave, thanks for explaining.
DeleteThere are records from the Chinnor chalk quarries. No doubt Martin Townsend can clarify.
