# American Snout (*libytheana carinenta*) The American Snout (Libytheana carinenta) is a remarkable and uniquely shaped butterfly best known for its prominent, elongated mouthparts that form a distinct "snout." Belonging to the brush-footed butterfly family, this species is a master of disguise, utilizing complex wing patterns and shapes to mimic dead leaves perfectly. Beyond its intriguing appearance, the American Snout is famous for its spectacular and unpredictable mass migrations. During certain years, population explosions triggered by specific weather patterns lead to millions of these butterflies taking to the skies in dark, cloud-like swarms. These breathtaking flights are a testament to the dynamic nature of insect life cycles and remain one of the most astonishing spectacles in the natural world. - **Category:** [Insects](https://www.snappit.app/explore/categories/insect) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Snaps:** 9 - **Habitat:** Found in open woodlands, brushy areas, and forest edges, particularly in regions where hackberry trees are abundant. ![American Snout](https://inaturalist-open-data.s3.amazonaws.com/photos/132180590/medium.jpg) Photo: Judy Gallagher, CC BY 4.0 · [iNaturalist](https://www.inaturalist.org/photos/132180590) ## Appearance This medium-sized butterfly has a wingspan of 3.5 to 5 centimeters. The most defining feature is its long, beak-like snout, which is composed of elongated labial palpi protruding from its head. The upper side of the wings is boldly patterned in black or dark brown with striking orange patches and white spots near the tips of the forewings. The underside of the wings is a mottled, dull brown and gray that flawlessly resembles a dried, dead leaf, complete with a dark line resembling a leaf vein. The forewings feature a distinctive squared-off tip, further enhancing its leafy disguise when resting. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Arthropoda - **Class:** Insecta - **Order:** Lepidoptera - **Family:** Nymphalidae - **Genus:** Libytheana ## Interesting facts - During massive population booms in Texas, swarms of American Snouts have been so dense that they block out the sun and cause streetlights to turn on during the day. - The snout is not actually a nose, but rather highly elongated labial palps, which are mouthparts covered in sensory receptors. - When frightened, the American Snout will often drop out of the air and fall directly into the leaf litter below, playing dead to become completely invisible to predators. ## Special abilities - **Dead Leaf Mimicry:** When resting with its wings closed, the butterfly perfectly mimics a dry leaf, utilizing its squared forewing tips and mottled brown underside to hide from predators. - **Mass Migration:** Capable of forming massive migratory swarms in late summer, with millions of individuals traveling together in numbers dense enough to obscure the sun. - **Elongated Labial Palpi:** Possesses specially adapted, highly elongated mouthparts that form a snout which helps break up its outline and enhances its dead-leaf camouflage. ## Measurements & details - **Length:** 1-2 cm - **Wingspan:** 3-5 cm - **Weight:** 0.0001-0.0003 kg - **Lifespan:** 0 years - **Speed:** 20 km/h - **Clutch Size:** 50-200 - **Incubation:** 4-8 days - **Migration Distance:** 800 km ## Diet & Feeding Caterpillars exclusively consume the foliage of hackberry trees, while adult butterflies feed on nectar from various flowers and extract minerals from damp soil. - **Age differences:** Larvae are obligate leaf-eaters (folivores), whereas adults shift entirely to a liquid diet of nectar and dissolved minerals. - **Primary Foods:** Hackberry leaves, Aster nectar, Goldenrod nectar, Dogwood nectar, Mineral-rich mud - **Foraging Method:** Foraging ## Ecological connections - **Host plant:** [Common Hackberry](https://www.snappit.app/explore/common-hackberry) (*Celtis occidentalis*) — Primary host plant for caterpillars. - **Eaten by:** [Eastern Bluebird](https://www.snappit.app/explore/eastern-bluebird) (*Sialia sialis*) — Preys on adult butterflies and caterpillars. - **Mutualism:** [Tall Goldenrod](https://www.snappit.app/explore/tall-goldenrod) (*Solidago altissima*) — Source of nectar for adult butterflies during late summer migrations. ## Safety **Danger:** 1/5 · Very low No special safety notes yet. ## Frequently Asked Questions ### How to identify American Snout?
