Definitely not a gray hairstreak which is an american species. I think auntnance may have it nailed http://s433.photobucket.com/albums/qq58/...
It's probably a gray hairsreak. I looked it up and I'm positive. I even did a picture here, and I labeled it that.
It looks like a type of hairstreak butterfly. It looks similar the USA Gray Hairstreak . Maybe Red-Lined Scrub. Unsure of butterflies in your area. Very pretty!
