American Snout, Libytheana carinenta (Cramer, 1777) is a member of the subfamily Libytheinae in the family Nymphalidae.

Flight time: Migrations occur from June to October and are thought to be triggered by drought followed by heavy summer rains: the droughts reduce a parasitoid that would otherwise limit butterfly populations, whereas the rain induces Spiny Hackberry, Celtis ehrenbergiana to grow new leaves that provide food for caterpillars . Furthermore, while the drought sends the butterflies into a sort of hibernation, the rain brings them out all at once to lay eggs, causing a population explosion. In Texas.

Larval host plants: Spiny Hackberry, Celtis ehrenbergiana. Are Celtis species on which the eggs are laid singly.
Traits: Massive migrations, often attract attention in Texas and Mexican newspapers.

Migratory: This species is known to be migratory, and some years the migrations are so huge that the sky darkens in some places. Migrations from southern Texas to the north occur at irregular intervals as southern populations explode, often affecting San Antonio, the Texas Hill Country, and Austin. Other migrations have been observed in Arizona, Kansas, and the Lake Erie Islands.

Distribution: Libytheana carinenta is found in both North and South America and is known to be migratory. This species is found in both North and South America. The other species in the genus are restricted to the Caribbean.

Amerikanske Snudesommerfugl, Libytheana carinenta (Cramer, 1777) er medlem af underfamilien Libytheinae i familien med Takvinger, Nymphalidae. Denne art findes i både Nord- og Sydamerika.

Flyvetid: Migrationer forekommer fra juni til oktober og menes at være udløst af tørke efterfulgt af kraftig sommerregn: Tørkene reducerer en parasitoid, der ellers ville begrænse sommerfuglebestandene, hvorimod regnen inducerer Spiny Hackberry, Celtis ehrenbergiana til at dyrke nye blade, der giver føde til larver. Ydermere, mens tørken sender sommerfuglene i en slags dvale, bringer regnen dem ud af det hele på én gang for at lægge æg, hvilket forårsager en befolkningseksplosion. I Texas.

Larveværtsplanterne: Spiny Hackberry, Celtis ehrenbergiana. Er Celtis-arter, hvorpå æggene lægges enkeltvis.

Træk: Massive migrationer, tiltrækker ofte opmærksomhed i Texas og mexicanske aviser.

Træk: Denne art er kendt for at være trækkende, og nogle år er vandringerne så enorme, at himlen nogle steder bliver mørkere. Migrationer fra det sydlige Texas mod nord forekommer med uregelmæssige intervaller, når sydlige befolkninger eksploderer, hvilket ofte påvirker San Antonio, Texas Hill Country og Austin. Andre migrationer er blevet observeret i Arizona, Kansas og Lake Erie Islands.
