Diet

• Adults feed mainly on rotting fruit, fermenting plant juices, and other moist organic fluids, rather than relying exclusively on flower nectar. They may also visit sap flows and animal droppings.

• The caterpillars feed almost exclusively on Cecropia trees.

• Females favor young Cecropia trees and saplings for egg-laying. The caterpillars may initially occur in small groups but generally become solitary or remain in small groups as they mature.

Range

• The Dirce Beauty has a broad Neotropical distribution extending from Mexico through Central America and the Caribbean to northern and central South America.

• It is an occasional to locally common butterfly in the Zihua area, particularly where Cecropia trees grow in disturbed woodland, forest gaps, and along streams.

Habitat

• It favors forest edges, clearings, secondary forest, stream margins, gardens, and other areas where pioneer Cecropia trees are abundant.

• It is particularly well adapted to recently disturbed vegetation because Cecropia often colonizes forest gaps and regenerating areas.

• Adults frequently perch head-down on tree trunks, often remaining motionless for surprisingly long periods.

Description

• A medium-sized butterfly with a wingspan of approximately 50–75 mm.

• The upper surface is predominantly dark brown to blackish, with a broad cream to yellowish transverse band crossing the forewings. A small pale spot near the forewing apex is also characteristic.

• The hindwings are dark, with lighter brown along portions of the margins.

• The underside is much more intricate, with a pale cream or yellowish background crossed by numerous narrow brown lines. Small dark spots with bluish or silvery centers occur on the hindwing.

• The distinctive striped underside and broad forewing band make it relatively easy to recognize.
