Definitely a Hairstreak, probably a Gray Hairstreak, but I'm not sure if you have similar species in your area. Remember, for absolute identification, I trust the experts at BAMONA. You can set up an account and submit sightings at www.butterfliesandmoths.org It really helps them to track what species are being found where. For those of you who live in more rural areas, I think it's great to contribute since there likely aren't many people in your area that are doing so. Florida has a lot of butterfly enthusiasts so I try to report only uncommon species or those I just can't identify (Skippers!) in order to learn. But I submit everything I see when I visit Grandma in WV since I imagine there aren't a lot of amateur lepidopterists in her area.
