The Red Banded Hairstreak, scientifically known as Calycopis cecrops, is a captivating species of butterfly with distinct markings on its wings. With its unique patterns, this small butterfly has charmed enthusiasts and researchers alike.
As its name suggests, the Red Banded Hairstreak sports a brilliant red band across the lower part of each hindwing. In addition to the eye-catching red band, the butterfly has a grey to brown base color with blue highlights towards the outer edges. These butterflies inhabit wooded areas and forest edges, where they feed on nectar from various flowering plants.
One notable characteristic of the Red Banded Hairstreak is its fascinating behavior. When resting on leaves, the butterfly moves its hindwings in a way that resembles an antennae-like motion, creating the illusion of a false head. This clever tactic helps the butterfly confuse predators and protect itself from potential threats.
Red Banded Hairstreak Overview
The Red-banded Hairstreak (scientific name: Calycopis cecrops) is a small butterfly belonging to the family Lycaenidae and genus Calycopis. This butterfly’s wingspan ranges from ¾ to 1 inch (1.9 – 2.5 cm), with distinctive patterns and colors on its wings, including an underwing surface that’s light gray-brown and a red or orange band edged with a thin white line that crosses both hind and forewings1. Here are some key features of the Red-banded Hairstreak:
- Family: Lycaenidae
- Genus: Calycopis
- Scientific name: Calycopis cecrops
- Order: Lepidoptera
- Wingspan: ¾ – 1 inch (1.9 – 2.5 cm)
The species name cecrops originated in ancient Greece, referring to a mythical king whose top half resembled a human and the bottom half looked like a fish or reptile2. This name could be related to the butterfly’s appearance, as hairstreaks often seem to have two heads, fooling predators into targeting the outer hindwing edge instead of the butterfly’s actual head3.
Various factors characterize these butterflies, such as:
- Unique patterns of white, black, and red-orange bands
- Bold eyespots on wings
- Small, threadlike hindwing “tails”

Red Banded Hairstreak
I love your site! My husband and I love the photos and appreciate the variety of insects you have. But I noticed today that you don’t seem to have a lot of hairstreaks. Here’s a shot of a red-banded hairstreak in our backyard in Hampton Virginia. I hope you can use it. Thanks for all your efforts.
Thanks for contributing to the elimination of the dearth of Hairstreaks on our site by submitting your lovely image of a Red Banded Hairstreak, Calycopsis cecrops.

Red Banded Hairstreak?
thanks so much for posting my photo of the wheelbug. I have another one to share with you. I believe this is a red-banded hairstreak (correct me if im wrong). there were two of them nectaring on some goldenrod the other day and i took some pics. I think this was my favorite one. Enjoy and thanks again for a wonderful website.
Hi again Mike,
Your Red Banded Hairstreak photo is awesome. Thanks for adding to our archive.

Subject: Which “Blue” is this butterfly?

Am I crazy, or did I just find a pair of Dusky Blue Groundstreaks in PA? A bee came along and startled them before I could really focus well, but the pattern is pretty distinctive. Butterfliesandmoths.org says they range from Venezuela to South Texas, and can stray to Kansas. Unless I’m mistaken these guys are doing some serious exploring.

Based on images posted to BugGuide, we are going to go with Red Banded Hairstreaks, Calycopis cecrops, a similar looking species in the same genus as the Dusky Blue Groundstreak. According to BugGuide: “Underside of both wings is dark grey with a red band crossing postmedian (i.e., more towards the back edge of the wing than the body). Above, some bright blue is visible in flight.” BugGuide also notes: “Eggs are laid on fallen leaves. They feed on detritus and on leaves of plants in the families Fagaceae, Anacardiaceae and Malvaceae. They feed on Mango (Mangifera indica), Brazilian Pepper (Schinus terebinthifolius), Winged Sumac (Rhus copallina), and other trees.” According to the Butterflies and Moths of North America, the range is: “Southeastern United States from Long Island south through Florida, west through entire area to southeast Kansas, eastern Oklahoma, and eastern Texas. Strays to eastern Nebraska, northern Illinois, and Michigan.” We only have two images of Red Banded Hairstreaks in our archive, and both were submitted in 2007. Because we must be away from the office for several days, we will be post-dating your submission to go live at the end of the week.
Thanks so much! Proof that I’m an amateur. Thanks for providing the expert input!
