Gulf Fritillary, Agraulis vanillae
The Gulf fritillary is a brightly colored butterfly common across extreme southern portions of the United States. At home in most open, sunny habitats, it frequents roadsides, disturbed sites, fields, open woodlands, pastures, yards, and parks. It is a regular in most butterfly gardens, including those in more urban settings. In Florida, it can be found in all 67 counties. The butterfly undergoes distinct seasonal movements each year. Adults move northward in spring and form temporarily breeding colonies throughout the southeast. Individual vagrants may occasionally reach into the central U.S., but rarely into the Midwest. Starting in late summer and continuing through fall, huge numbers of adults migrate southward into peninsular Florida. Adults overwinter in frost-free portions of their range.
