The Common Grass Blue is one of the most common butterflies of Australia. It can be found in large numbers in basically every grassy spot across the country, although it appears to be somewhat less common in south-western WA. In warm and sunny weather, males permanently flutter around near the ground, whereas in cooler conditions they usually rest in the grass, often with their wings half open.
The Common Grass Blue can be easily distinguished from other species by the faint and indistinct spots on the underside of the wings, although the spots are highly variable and occasionally can be very prominent and dark.
