The Gulf Fritillary is a resident throughout the southern United States down into Mexico, Central America, the West Indies, and South America.
The Gulf Fritillary prefers subtropical second growth, woodland edges, brushy fields, and city gardens.
The Gulf Artillary has pointed forewings and a wing span of 2.0 to 2.5 inches. The upperside of the butterfly is bright orange with brown and black markings. The underside is a deeper color with distinct elongated silver spots. Females are darker with heavier markings.
Males search for freshly emerged females. The eggs are laid singly on passion-vines. The egg of the Gulf Fritillary is yellow, oblong, and ribbed. Mature larvae are a dark brown or black with red-orange stripes and rows of complex black spines.
The Gulf Fritillary migrates northward to the Central U.S. It can be found in such areas as the Great Basin, the Rockies, the Midwestern United States, and the mid-Atlantic States.
The Gulf Fritillary feeds on Maypops and other passion-vine species. Passion Flower is the larval foodplant.

The Gulf Artillary belongs to the subfamily Heliconiinae. Members of this group are unique for collecting pollen in their proboscis. After the pollen is collected it is absorbed through the walls of the proboscis.

forest biomes are dominated by trees, otherwise forest biomes can vary widely in amount of precipitation and seasonality.
the area in which the animal is naturally found, the region in which it is endemic.
rainforests, both temperate and tropical, are dominated by trees often forming a closed canopy with little light reaching the ground. Epiphytes and climbing plants are also abundant. Precipitation is typically not limiting, but may be somewhat seasonal.
scrub forests develop in areas that experience dry seasons.
A terrestrial biome. Savannas are grasslands with scattered individual trees that do not form a closed canopy. Extensive savannas are found in parts of subtropical and tropical Africa and South America, and in Australia.
A grassland with scattered trees or scattered clumps of trees, a type of community intermediate between grassland and forest. See also Tropical savanna and grassland biome.
A terrestrial biome found in temperate latitudes (>23.5° N or S latitude). Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. Fire and grazing are important in the long-term maintenance of grasslands.
