Diet

• Caterpillars feed on pipevines in the family Aristolochiaceae.

• Adults obtain nectar from flowers and may also visit damp ground for moisture and minerals.

Range

• Parides montezuma occurs from Mexico through Central America to Costa Rica.

• It is primarily associated with the Pacific and southern regions of Mexico and is more common in Mexico than farther south.

• Guerrero is within its range, and it occurs in the Zihua area.

Habitat

• It is primarily a butterfly of tropical dry forest and other seasonally dry woodland.

• It occurs from sea level to approximately 700 metres.

• Forest edges, clearings, river valleys and areas supporting Aristolochia vines provide suitable habitat.

• In the Zihua area it is associated with warm, relatively dry tropical vegetation.

Description

• A large swallowtail with a wingspan of approximately 70–85 mm.

• The wings are predominantly velvety black, with a subtle greenish or bluish sheen, particularly toward the bases of the wings.

• The hindwing has a conspicuous series of red to orange-red submarginal crescents. These markings are the principal feature distinguishing it from many other black Parides.

• The hindwings are essentially tailless or have only a very short projection.

• The underside is similar to the upperside, although the red hindwing markings can be more extensive and additional pale markings may be visible.
