Genus Myzocallis has 37 species. Once entomologist Dr. Chris Dietrich (http://www.inhs.uiuc.edu/staff/index.php?action=list&user_name=chdietri) told me this was an aphid (duh!) it was fairly easy to tentatively identify further (http://www.fs.fed.us/r8/foresthealth/pubs/oakpests/p29.html). Can anyone out there simply state how it is some have wings and some do not? (Note: in the background are Oak Treehopper nymphs.)
