Phyllopalpus pulchellus - Red-headed Bush Cricket. 8 mm long (not counting appendages).

According to BugGuide, this sp is "found in vegetation near streams and marshes, about a meter above the ground". With the Raritan close to 30' above flood stage, this guy was undoubtedly flushed from its former home, ending up in my backyard a few hundred meters away. I noticed several unusual bugs showing up here & suspected it was because of the hurricane, but didn't expect to confirm it so easily!

Also didn't expect to ID this guy so easily: had no clue, beyond long-horned orthoptera, but a BugGuide search on "red black cricket" produced an instant match.
