Migration and Global warming


If you click on this picture you should be able to read this very interesting article.Closer to home the number of Butterfly species in Calderdale is definitely on the increase and new moth species are also on the increase ie Light Brown Apple Moth,Blairs Shoulder Knot,Black rustic etc.But the numbers of common moths are on the decline through habitat loss and farming practises.This is why all the information/data we collect is locally very important .If any one has records for Calderdale(old or new) please could you send them to me and please include date,how many,how you saw it ie daytime obsevation,light trap or sugaring etc.Many thanks Andy
