The Gulf FritillaryAndrew V. Z. Brower and Margarita Beltrán
The Gulf fritillary, Agraulis vanillae, is a widespread, geographically variable neotropical species that occurs from the south central U. S. to southern South America. Lamas (2004) lists a second, undescribed species in the genus from Peru.
Early stages: Eggs are yellow and approximately 1 x 0.8 mm (h x w). Females place eggs singly on leaves of the host plant. Mature larvae are approximately 1.2 cm long. Caterpillars are gregarious in small numbers (Brown, 1981).

Agraulis occurs in scrubs and fields. Usually individuals fly rapidly. Females mate multiply, and adults roost at night in loose groups, lower than 2 m above the ground in grass blades and leaves (Brown, 1981).
Hostplant: Agraulis is polyphagous, and larvae feed primarily on plants from the subgenera Granadilla and Distephana (Passifloraceae) (Brown, 1981).
