I am working on a second edition of my Naturalists' Handbook 24-Ants.  In the new ones, the colour paintings and line drawings (except for keys) are being replaced by photos.  I am hoping to take most of these and I am wondering if anyone is prepared to help me with precise locations of nests etc. for the more Southern and rarer species.  I live in Yorkshire so have access to only about 17 species in my own county.  I will send a list of what I need or post it on here later.  Any information would be helpful, but I have had very good experiences with lat./long. data and 10 digit grid refs. 

Thanks in advance for any help you can give.
