It was a warm, almost muggy night. It was the kind of night that brought all sorts of partygoers to my deck lights. This is one of two handsome Ichneumon males, sharing the front landing, waiting for the ladies to arrive. The front deck is lit by a compact florescent that emits a soft yellowish light - the back deck is lit by one that gives off a colder daylight blue light and seems to attract a different sort of partygoer.

I looked for a match in the guide and came up with Ophioninae.
