We are now including Three Pages of information on Exuvia


   
    The first page is for U.K.species,now we are adding pictures of Emergents,where we have them.

      The second page is the Japanese exhibits,from Yoshihiko.

      The third page contains a copy of the Field Notes on Exuvia,written by Gill Brooks,with some extra data from other sources.(NOTE: these two pages are about 110kbs each,which may make a slow download!)
