Scales on a Red Oak

One of the oaks from the 2009 planting is heavily infested with some type of lecanium scale. The red ants(Genus Myrmica) that seem to be common on the site are feeding off the honeydew these scales excrete. The local Macoun Field Club has a fascinating write-up about an infestation of these scales that occured in 2006 and 2007.
