Hessel’s Hairstreak

May 2021

The Hessel’s Hairstreak (Callophrys hesseli) is a brilliant emerald green and shiny brown tiny hairstreak butterfly with white and brown streaking amid the blue-green underside scaling. This stunning species can be found near its host plant Atlantic White-cedar feeding on flowers like the Sand Myrtle (Leiophyllum buxifolium) in the photo, or blueberry.

Though they are strikingly marked, the combination of small size, color combo, and fast flight can make them very hard to track. They will retreat to the Cedar trees for cover or perches to defend territory, and can zoom through the flower patches with short flights that take them right out of sight. When hairstreaks angle their closed wings sometimes they are almost invisible from above - especially green hairstreaks amid partially shaded leaves. Can you spot the Hessel’s Hairstreak in the image? Upon close inspection it is obvious, but standing even a few feet away makes picking out this species a real challenge!!
