Fun Facts
Did You Know?
Smooth sumac, Rhus glabra, and winged sumac, Rhus copallinum, both grow throughout North Louisiana's 26 parishes in old field margins, woodland edges, roadsides, and disturbed ground. Sumac produces dense clusters of tiny flowers in July and August that draw many insect species. The red-banded hairstreak uses sumac both as an associated plant in breeding habitat, where sumac's abundant fallen leaf litter provides caterpillar food, and as an adult nectar source at the summer flower clusters
If This Animal Could Talk...
"Watch closely, respect my space, and let my habitat explain the rest of the story."
The red-banded hairstreak does not look like other hairstreaks. Most North Louisiana hairstreaks come in gray or brown with delicate underside lines and require close examination to distinguish. Calycopis cecrops announces itself with a bold red-orange band crossing both wings on the underside, visible from several feet on a perched individual, making it one of the easier small butterflies in the region to name at a distance.
That red band earns immediate identification. Two tails per hindwing, one long and one short, add the structural character that places it in the hairstreak family. The whole package comes in a wingspan of barely an inch. The red-banded hairstreak asks to be found and then rewards the finding with a pattern that would look at home on something twice its size.
A Few More Facts
How they hunt and forage: Adults nectar at small, open-faced flowers in woodland edge and semi-open habitats. Sumac flowers draw adults reliably in summer, sumac blooms in compact, dense clusters that provide multiple nectaring stations in a small area, and adult red-banded hairstreaks working a sumac cluster in July represent one of the most productive close-observation situations for the species. Wild carrot, native goldenrod, native asters, and various other small-flowered plants at woodland edges also draw adults. Adults mud-puddle at damp bare soil, appearing at the same productive mud sites as eastern tailed-blues and summer azures. A three-species mud puddle in July with all three small butterfly groups, azures, tailed-blues, and hairstreaks, provides the direct comparison needed to calibrate identification for all three. The red-banded hairstreak at the puddle carries the red band visible on closed wings even from several feet, making it identifiable before close approach.
Live birth or eggs? no
When young are born: The following spring's adults emerge from those chrysalises in late March, and the cycle restarts at the same woodland edge sumac stands that produced the previous generation's encounters.Documentation NotesRed-banded hairstreak records from North Louisiana appear in citizen science databases below the actual abundance level of the species, for the usual reasons that small woodland-edge butterflies get underrecorded: observer effort concentrates at open-habitat flower sites rather than at the shaded sumac stands and woodland edge litter margins where this species spends most of its time.Observations from July and August at flowering sumac stands throughout the 26 parishes, submitted to iNaturalist with photographs showing the red band and the hindwing tail bases, build a regional distribution record for a species whose actual abundance in the 26-parish region remains underdocumented.
What Is the Red-Banded Hairstreak Often Confused With?
Adults span seven-eighths to one and one-eighth inches, at the small end of even the small-butterfly community in North Louisiana. The upperside shows dark gray-blue, visible briefly in flight before the butterfly lands and closes its wings. The underside, the view available on a perched individual, shows the identification-confirming pattern: a broad red-orange band crossing both the forewing and the hindwing, bordered on the inner side by a black line and on the outer side by a white line. That three-color band, red-orange flanked by black and white, crosses the wing in a way that no other North Louisiana butterfly replicates. Below the band on the hindwing, a row of small black spots rimmed with metallic blue-green iridescence sits near the tail bases.

Red-banded hairstreaks at sumac flower clusters produce soft wing-sounds on landing audible at very close range in still conditions. The red-orange band on the closed-wing underside locates perched individuals against green vegetation from several feet without requiring the fine-grained visual resolution that other hairstreak species' pattern features demand.
Any sumac stand in flower at a woodland edge throughout the 26 parishes from July through September. Any productive mud puddle at a woodland edge from late spring through fall. Any native goldenrod or aster patch at a woodland margin in August through October. The species finds those resources. The observer finds the species by finding those resources and checking the closed-wing underside for the band that no other small butterfly in North Louisiana produces.

Frequently Asked Questions
Does Red-Banded Hairstreak live in North Louisiana?
Yes. Most North Louisiana hairstreaks come in gray or brown with delicate underside lines and require close examination to distinguish. Calycopis cecrops ranges across the southeastern United States and throughout North Louisiana's 26 parishes it breeds wherever dead plant material accumulates at woodland edges, fallen leaves, decaying wood, dried stems, which covers essentially every forest edge and disturbed woodland margin in the region.
Calycopis cecrops sits among the most common hairstreaks in North Louisiana and among the most under-documented, because most observers do not routinely examine small butterflies in the partial shade of woodland margins.
How do you identify Red-Banded Hairstreak?
Adults span seven-eighths to one and one-eighth inches, at the small end of even the small-butterfly community in North Louisiana. The upperside shows dark gray-blue, visible briefly in flight before the butterfly lands and closes its wings.

Adults nectar at small, open-faced flowers in woodland edge and semi-open habitats.

The red-banded hairstreak at the puddle carries the red band visible on closed wings even from several feet, making it identifiable before close approach.
Is Red-Banded Hairstreak dangerous to people?
No. This species is not dangerous to people when it is observed without handling or disturbance
