Description and Identification
Caterpillar
The Variegated Fritillary caterpillar is notable for its brownish copper color, adorned with white lines and fine black spots. The body features small, black, spine-like protrusions, adding to its distinctive appearance.
Pupa
The chrysalis stage presents a shiny white casing dotted with bright orange to copper spots, each accented with tiny black spots. This phase of their lifecycle occurs as they hang from the upper side of leaves, preparing for their final transformation.
Adult Butterfly
Sexual Dimorphism: This species does not exhibit sexual dimorphism, with males and females appearing similar in coloration and pattern.
Color and Appearance: The adult Variegated Fritillary boasts a checkered pattern of black and orange on its wings. The dorsal side features dark spots and lines, while the ventral side reveals a more subdued palette with specific markings on the fore and hindwings.
Average Wingspan: Adults span approximately 1.75–2.25 inches (44–57 mm), a size that facilitates their slow and somewhat erratic flight pattern.
Flight Pattern: The butterfly’s flight is characterized as slow and erratic, adding an unpredictable beauty to their presence in nature.
Eggs
The pale-green or cream-colored eggs are delicately laid on the stems and leaves of host plants, marking the beginning of the lifecycle.
