Scientific Classification


  • Family: Nymphalidae
  • Genus: Boloria
  • Scientific Name: Boloria bellona

Overview

Belonging to the diverse fritillary species, the Meadow Fritillary thrives in sunny, open habitats where they engage in their low, yet adept flight. This species demonstrates a fascinating lifecycle that includes distinct stages from a uniquely textured caterpillar to a visually striking adult. Their reliance on specific host plants and their adaptive strategies for survival through different seasons underscore their ecological significance and the intricate balance within their ecosystems.

Description and Identification

Caterpillar

The larval stage presents a dark, either black or brownish-black body, adorned with irregular ridges. The caterpillar is also notable for its fine, tufted hairs along its back, arranged in a linear pattern. As a strategy against the cold, these larvae enter a period of hibernation during winter.

Pupa

Resembling an elongated seashell, the chrysalis varies in color from dark to yellowish to light brown. Its surface is textured with ridge-like unevenness, an adaptation that may provide camouflage. This stage is typically spent suspended from a twig or branch of the host plant, marking a transitional phase in the butterfly’s development.

Adult Butterfly

Sexual Dimorphism: This species exhibits sexual dimorphism, where males and females can be distinguished by physical appearance.

Color and Appearance: In flight or when resting with wings spread, the forewings display a squared-off tip, and both pairs of wings boast a reddish-orange hue with dense black markings. The underside of the hindwings reveals a complex pattern in orange and purplish brown, featuring an off-white basal patch. Males are distinguished by a prominent, bright yellow border on the underside of their wings.

Flight Pattern: Characterized by a low, medium-speed flight, this species maneuvers through its habitat with grace and agility.

Eggs

The eggs are a greenish-yellow hue, delicately laid on twigs and plants associated with their host species, initiating the life cycle anew.

How to Identify Meadow Fritillary?

Identifying the Meadow Fritillary can be an engaging activity for butterfly enthusiasts. Look for their distinct reddish-orange wings adorned with black markings, a unique combination among North American butterflies. The squared-off forewing tips are a notable characteristic when the wings are spread. In males, the bright yellow border underneath the wings is a key identifier. Observing their flight pattern can also aid identification; their medium-paced, low flight is characteristic of their species. Additionally, their presence in specific habitats, such as wet, open fields and along streamsides, can indicate their likelihood. To confidently identify these butterflies, familiarize yourself with their lifecycle stages, as each offers distinct features from the caterpillar’s ridged body to the pupa’s seashell-like appearance.
