Calling All Lepidopterists! Can You Identify This Butterfly?

I was going to write about the lovely Egyptian Verbena blooming in my front gardens, which I transplanted from my mother-in-law’s garden in Durham … but when I was looking at my photos, I realized I had a great shot of a butterfly. So I decided to investigate. 

I’m no expert—I can identify a yellow monarch with the best of you—but I think I may have found an anomaly and was hoping for a little input from my fellow gardeners. 

Can you identify the butterfly in the image?

I went to Butterflies and Moths of North America, a great site that has every butterfly and moth referenced and cross-referenced and Gantt charted easily enough that even I could understand how to search and discover. 

To my inexpert eye, it looks like I’ve got a Marius Hairstreak. Further investigation has led me to believe I can base this decision on the fact that my butterfly (pictured) has dark postmedian dashes on both wings, and two submarginal eyespots on the hindwing. 

Working against my iffy identification are the facts that Hairstreaks have light blue undersides and mine has a khaki undercarriage … and, oh yeah, the map shows that documented records for the Marius Hairstreak place their range from Paraguay north to Sonora, Mexico with  rare strays being found up to South Texas. So unless this is a sign of global warming and a temperature shift, OR I've identified my butterfly incorrectly, it seems unusual that we'd have a Marius Hairstreak here in Wake County. 

• Do you think I’ve identified my butterfly correctly?
• If not, what kind of little critter is supporting my ecosystem?
