Every day I take several trips to my backyard to check the pool for any insects or spiders that may have fallen in. Today (11-29-2012) I found this little insect which is one I have never seen before. I’ve tried doing a bit of investigating on my own, but this has me stumped.

Giant Bark Aphid

Hi Casey,
According to BugGuide, the Giant Bark Aphid,
Longistigma caryae, 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.”  The host trees, according to BugGuide, are:  “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.”
