Gray Cracker
Gray Cracker (Hamadryas februa ferentina: Nymphalidae) This extremely cryptic butterfly has a wingspan of 7.0-8.9 cm (2.8-3.5 in). It is named for the sound it makes when taking flight and in flight. Adults almost always rest on tree trunks with their heads pointing downward and their wings spread open. Dont look for this butterfly around flowers but around rotting fruit, mud, or dung. It is frequent along both the Pacific and Atlantic sides in lowlands but can range up to 1,000 m ( 3,281 ft) elevation. Photographed on lodge grounds at Si Como No Lodge in Quepos, Puntarenas Province, Costa Rica. Low wet rain forest at ca. 26 m (85 ft) elevation.

A great shot of this impressive butterfly. The pattern of its wings would make it difficult to spot on a tree-trunk.
 
Great BF, Stanley; interesting info too, well done. I wonder if there's predators that listen for the cracking sound.
