## Summary

The Gulf fritillary or passion butterfly (Dione vanillae or Agraulis vanillae in other taxonomies) is a bright orange butterfly in the subfamily Heliconiinae of the family Nymphalidae. That subfamily was formerly set apart as a separate family, the Heliconiidae. The Heliconiinae are "longwing butterflies", which have long, narrow wings compared to other butterflies.
Dione vanillae is most commonly found in the southern areas of the United States, specifically in many regions of Florida and Texas.
Gulf fritillaries have a chemical defense mechanism in which they release odorous chemicals in response to predator sightings…
