Green Hairstreak (Callophrys rubi)

The Green Hairstreak (Callophrys rubi) is a charming species of butterfly known for its vibrant green coloration and delicate appearance. Here’s a detailed description:

• Appearance: The Green Hairstreak is a small butterfly with a wingspan typically ranging from 25 to 30 millimeters. It has predominantly green wings with a subtle iridescence, giving it a shimmering appearance in sunlight. The upper side of the wings is usually a brighter green, while the underside is paler with a row of white or pale yellow spots along the margins. In some individuals, the undersides of the wings may also feature orange or reddish spots near the body.
• Habitat: Green Hairstreaks are often found in a variety of open habitats, including grasslands, heathlands, scrublands, and woodland edges. They have a preference for areas with low-growing vegetation, particularly those with abundant flowering plants and shrubs, where they can find nectar sources and suitable egg-laying sites.
• Range: This butterfly species is native to various parts of Europe, including the British Isles, Scandinavia, Central Europe, and extending into Asia. It is widespread within its range and can be found in suitable habitats across different countries.
• Behavior: Green Hairstreaks are agile fliers and can often be seen fluttering among vegetation or perching on low branches and leaves. They have a rapid and erratic flight pattern, making them challenging to follow. Adults feed primarily on flower nectar, using their long proboscis to reach deep into the floral tubes.
• Life Cycle: The Green Hairstreak undergoes a complete metamorphosis, progressing through egg, larva (caterpillar), pupa (chrysalis), and adult stages. The caterpillars feed on the leaves of various plant species, while the adults primarily feed on flower nectar.
• Conservation: While the Green Hairstreak is not considered globally threatened, it may face localized threats due to habitat loss, fragmentation, and changes in land use. Conservation efforts aimed at preserving and restoring butterfly-friendly habitats, including the planting of nectar-rich flowers and maintaining suitable larval host plants, can benefit not only the Green Hairstreak but also other butterfly species.

The Green Hairstreak is admired by enthusiasts and researchers for its beauty, behavior, and ecological importance as a pollinator. Understanding its habitat requirements and conservation needs is crucial for ensuring its long-term survival.
