Treehopper - Enchenopa on-ptelea

Treehopper - Enchenopa on-ptelea
Bunker Hill Forest Preserve, Chicago, Cook County, Illinois, USA
August 28, 2005
Dr Hamilton, these four images are of the Enchenopa that we find on Wafer Ash, Ptelea trifoliata, on the edge of an open oak savanna in the Cook County Forest Preserves, within the city limits of Chicago, north side. They always seem to be in association with the white scale insect in the image.
