Lately we have seen this butterfly in our backyard:
It is the Red-banded Hairstreak (Calycopis cecrops). They are one of the most common hairstreaks found throughout the southeastern United States. You will often see them in dry open wooded areas and in wooded neighborhoods.
They are called hairstreaks due to the having tiny hair-like tails on their hind wings. Another characteristic of hairstreak butterflies is that they will rub their hind wings together when perched.
The adults feed on nectar from a variety of flowers such as milkweed and yarrow. The caterpillar larvae are reported to feed on the dead leaves of wax myrtle and sumac trees, as well as detritus in the leaf litter.
