From my upcoming, "Butterflies of the World v1"... Here we have the Gray Hairstreak on some Justica californica (Chuparosa)... and yes, it was a challenge to pose this tiny butterfly on one of the chuparosa flowers. It is one of the most common hairstreaks in North America, ranging over nearly the entire continent. It also occurs throughout Central America and in northern South America. It lives in a wide range of habitats ranging from tropical forests and mountains to temperate woodland areas and meadows, as well as cities and farmland. Hairstreaks get their name from the tiny hair-like extensions on their hind pair of wings.
