Birds, spiders, other insects.

Worth knowing

• The 'fritillary' part of their name means 'checkered' or 'spotted'.
• They lay their eggs on or near violet plants, not directly on the leaves.
• The caterpillars hide during the day and feed at night to avoid predators.
• The underside of their wings has striking silver spots that catch the light.
• They often bask in the sun to warm up their wings for flight.
• Males fly faster than females, especially when looking for a mate.

Why it matters

Great Spangled Fritillaries are important pollinators, helping flowers and plants make seeds. Their caterpillars eat violet leaves, helping control plant growth.
