American Snout Butterfly

The American Snout Butterfly, Libytheana carinenta, is commonly seen nectarine at flowers in areas where hackberry trees are abundant. The orange and black butterflies have labial palps that extend forward and are much longer than any of the similar butterflies in Indiana. When the wings are closed, they resemble dead leaves. The butterfly can be found throughout the Western Hemisphere from Argentina to Canada.

American Snout butterflies occasionally have large population explosions in Texas. Large populations are associated with a drought period that reduces the parasitoid populations followed by wet weather that promotes new growth of spiny hackberry, a shrub host. The new growth is optimal for American Snout growth and reproduction. Large flights of perhaps millions of American Snout Butterflies have been observed.
