Leaf-Footed Bug

One of our native leaf-footed bugs, Acanthocephala terminalis is just appearing as adults in my area.  Several molts (instars) occur before they reach this adult stage.  This one was on my house foundation this afternoon.  It is larger and broader then the Western Conifer Seed Bug (see http://naturalistguy.com/2010/11/05/1740/) that recently extended its range to the Eastern US.  This leaf-footed bug seems to feed on sumacs and other woodland plants- without being much a pest to humans.  It is a true bug (Heteroptera), and is in the Coreidae family.  The terminal antennae segment is orange, and this is a good field ID for this beauty.  Below here, is a late instar of a leaf-footed seed bug (different species), to show the wings developing. Enjoy.  NG.
