The Holly Blue is frequently seen in suburban gardens where its larval foodplants (Holly and Ivy) occur. In flight, it has a silvery appearance.
The adult Holly Blue emerges early in spring, well before any other blue butterflies. Unlike other blues, the Holly Blue tends to fly high up around trees and bushes in full sunlight. The males can sometimes be found at ground level taking salts from dried up puddles in summer.
The Holly Blue can be found almost anywhere, even in city centres. Gardens, public parks, disused railway lines, hedgerows, field margins and woodland rides where both Ivy and Holly (the larval foodplants) can be found are the best places to find this butterfly.
The larvae of the Holly Blue feed on Holly (Ilex aquifolium) and Ivy (Hedera helix). In the spring, eggs are laid and larvae feed on developing flower buds and berries of Holly from April to early June while in the autumn, eggs are laid and larvae feed on developing flower buds and berries of Ivy between August and mid to late September.
Growing a Holly (Ilex aquifolium) and Ivy (Hedera helix) bush in your garden will be highly attractive to this species. The Holly Blue is easy to encourage to breed in suburban gardens.
