Hamadryas guatemalena (H.W. Bates, 1864)
Family: Nymphalidae
Subfamily: Biblidinae
Identification: Upper surface is patterned with brown, gray, and tan; outer half of forewing is lighter and there is a red bar in the cell. Upper hindwing has eyespots with a mottled brown and white center circled in blue, then a wide black ring, and outside of that, another blue ring. Underside is tan and white; forewing with a large white spot below apex, hindwing with submarginal black rings.
Wing Span: 3 - 3 7/8 inches (7.6 - 9.8 cm).
Life History: Eggs are laid singly underneath mature leaves of the host plant. Adults perch on tree trunks head downward with their wings spread open; males await females and make a cracking noise when they dart out at other insects. Before dark, adults gather on a single tree, then disperse to roost in nearby trees or shrubs.
