Dear forum users!
I am very interested in all insects in wasp and hornet nests (hibernators, parasites, decompositors). Can you pick up the nest, put it into plastic bag and add all data: locality, description of site, date of collection and name of the collector? There are two ways: (i) Send complete nests to me. (ii) Take out all the insects from every nest + unhatched wasps from their cells (necessary for host species identification) and send it to me. More info see, e. g., in my contribution on page 14 in BWARS Newsletter, Spring 2010.
Thanks to everybody willing to help me!
