Ypthima huebneri

Common four-ring

The common four-ring gets its name from the four yellow-ringed eyespots on its hindwing underside, one fewer than its five-ringed relative.

Size30 to 39 mm wingspan
WhenJanuary to December

The common four-ring is a small, greyish brown satyrid with a large twin-pupilled, yellow-ringed eyespot near the forewing tip and, on the underside hindwing, four smaller yellow-ringed eyespots arranged in a gentle curve; fine dark striae cross the pale grey-brown underside.

Caterpillars feed on lawn and roadside grasses such as Bermuda grass and other low grasses, and the adults fly with a weak, jerky flight low over grassy ground, resting with wings closed for long spells before opening them fully to bask in the sun.
