Red Admiral Butterfly | Vanessa atalanta EGGS
Vanessa atalanta, commonly known as the Red Admiral, is a striking butterfly belonging to the family Nymphalidae. This widespread and well-loved species is found across Europe, North America, Asia, and North Africa. Its bold coloration and migratory behavior make it a notable presence in gardens and parks during the spring through to autumn. It can even be observed in flight during mild winter weather.
The Red Admiral is medium in size, with a wingspan of 5–6.5 cm. Its forewings are predominantly black with bright red bands and white spots near the tips, while the hindwings are black with red margins and a pattern of blue spots near the edges. This vibrant coloration not only makes the butterfly easily recognizable but also plays a role in deterring predators.
Vanessa atalanta is known for its strong migratory behavior, with individuals traveling long distances between breeding and overwintering grounds. In temperate regions, it often migrates north in spring and returns south in autumn. The butterfly is highly adaptable and can be found in a variety of habitats, including gardens, woodlands, meadows, rural and coastal areas.
The larvae of the Red Admiral feed primarily on nettles (Urtica dioica) and other plants in the nettle family. The caterpillars are spiny and dark, with patterns of yellow and white markings. They construct shelters by folding leaves and binding them with silk, providing protection as they grow and develop. Once fully grown, the caterpillars pupate into chrysalides, from which the adult butterflies emerge after about 2-3 weeks.
Adults are active and fast fliers, often seen basking in the sun or visiting flowers for nectar. They are particularly attracted to plants like buddleia, daisies, and thistles. In autumn, they also feed on overripe fruit, which provides a valuable energy source for migration or overwintering. In milder climates, some Red Admirals can survive the winter as adults, reemerging on warm days.
