Apologies for cross-posting. I wonder if anyone can help Malcolm Burrows
who is searching for specimens of Cercopis vulnerata and other hoppers for
his studies on their locomotion. I can send anyone a copy of a fascinating
paper by him on the subject - contact me off group. In case anyone is
unaware of C. vulnerata, there is a picture and info at
