Chevronned Gum leafhopper

Thanks MacChristiansen and S Frazier... Good question Scott - I've been wondering the same. From memory I think they interact often between adult and earlier forms but could be wrong. I guess you'd really need to watch them full time possibly for weeks :-( maybe moults happen incredibly frequently? maybe there are some inate grouping tendencies keeping them on the same stems?... Most clusters are mixed but sometimes it is just one instar... so many questions ! Do you think I should take it out of 'invert brooders' mission until the science is done?.... just had another thought... the adults hang around the youngsters because they have lost their nectar-making talent... %#!-
