The butterfly you are referring to, an exquisite orange species adorned with distinctive black spots, is known as the Dark Green Fritillary.
Discovering the Dark Green Fritillary
This beautiful insect is a common sight in various open landscapes, recognized for its vibrant coloration and graceful flight. Despite its primary orange and black appearance, its unique common name stems from a specific feature on its underside.
Key Characteristics of the Dark Green Fritillary
The Dark Green Fritillary (Argynnis aglaja) stands out among its kin. Here are some of its defining attributes:
- Appearance: Its upper wings are a striking orange, intricately patterned with bold black spots and markings. This vibrant display makes it easily noticeable against green foliage.
- Name Origin: The most intriguing aspect of its name comes from the undersides of its hindwings, which exhibit a distinct dark green hue. This coloration is particularly visible when the butterfly rests with its wings closed.
- Flight Pattern: Known as a strong flier, the Dark Green Fritillary can often be seen gracefully gliding and darting through its preferred environments.
- Habitat: It thrives in open, grassy habitats, including meadows, pastures, downlands, and woodland clearings, where it can find ample nectar sources and host plants.
Scientific Classification and Distribution
As part of the Nymphalidae family, commonly known as brush-footed butterflies, the Dark Green Fritillary is scientifically classified as Argynnis aglaja. It enjoys a wide distribution across much of Europe and Asia, adapting to various temperate conditions.

Life Cycle and Ecology
The life cycle of the Dark Green Fritillary, like many butterflies, involves a fascinating transformation:
- Host Plants: The caterpillars primarily feed on species of violets (Viola spp.), which are crucial for their development.
- Adult Diet: Adult butterflies sustain themselves by nectaring on a variety of wildflowers, with a particular fondness for thistles and knapweeds.
- Flight Period: Typically, adults are on the wing from early summer through late summer, often seen between June and August, depending on the geographical location and climate.
Identifying the Dark Green Fritillary
While several fritillary species share similar orange and black patterns, the dark green hue on the underside of the hindwings is the definitive characteristic for identifying the Dark Green Fritillary. This feature helps distinguish it from other fritillaries, such as the High Brown Fritillary or Silver-washed Fritillary. Observing these subtle differences is key for accurate identification in the field.
