We really do try to respond to as many requests as possible.  Thanks for resubmitting your image.  This is a Giant Bark Aphid,  Longistigma caryae, which you can find pictured on BugGuide.  According to BugGuide:  “This is the largest aphid in North America with adults averaging about 1/4 inch long. They also have long legs which makes them appear even larger. Males and some females are winged but egg laying females are wingless. They are brown with black markings (giving them somewhat of a mottled appearance) and have short, black cornicles. When alive they are often partially covered with a bluish white, waxy secretion. ” BugGuide also notes that host plants include:  “American elm, pin oak, live oak, post oak, blackjack oak, pecan, hickory, sycamore, and golden rain tree. Other trees which might be infested include maple, basswood, birch, beech, walnut, chestnut, and willow. ”
