Great Spangled Fritillary

Speyeria cybele

Nymphalidae

A large orange butterfly with silver spangles on the underside of its hind wings — hence the name. Common at midsummer nectar plants, especially milkweeds and Joe-Pye Weed, where you'll see them working the flowers alongside monarchs and swallowtails.

Identify by

How to spot one.

  • 3.5–4 inch wingspan

  • Bright orange upper wings with black lines and spots

  • Silver-white spots on the underside of hind wings — visible when perched

  • Larger than most other orange butterflies

Life & behavior

How it lives.

One brood per year. Females lay eggs on or near violets in late summer; caterpillars hatch, take one meal, then overwinter as tiny larvae in leaf litter. They resume feeding on violet leaves the following spring — which is why leaf litter matters.
