Butterflies - Green Hairstreak (Callophrys rubi)

This little butterfly is easily overlooked due to its colouration. The upper sides of its wings are brown but this is rarely seen since the Green Hairstreak always closes its wings when not in flight. The green undersides are a vivid iridescent metallic green often edged in tan brown with white spots forming a feint white 'streak' on the hind wings. The extent of the white marking is highly variable and in some cases almost absent.

Its flight is rapid and jerky. Territorial males often return to the same perch while the females are more often seen when searching for larval food plants upon which to lay their eggs.
