The Meadow Argus Caterpillar is black or brown, and spiky. The spikes are short, thick, and branched. There is even a pair on its black head. Small blue-white spots dot the surface, and there are larger whitish marks underneath. There may also be yellow areas at the base of the spikes. There is a narrow yellow neck between the head and thorax.
This Caterpillar feeds on many plants, both native and introduced, of the garden and the roadside, including :
When not feeding, the Caterpillar hides under a leaf or at the base of the foodplant. The Caterpillar can mature in about two weeks, growing to a length of about 4 cms.
It pupates on the underside of a stem or leaf of its foodplant, dangling by its cremaster to do so. The pupa is dark grey with white mottling. It is rough and has a knobbly dorsal surface. It has the appearance of a dead crumpled leaf as it swings with the plant in the wind. Its length is about 1.5 cms. The pupal period can be ten days, in February in Melbourne.
The butterfly emerges after about two weeks. The male and female are similar in appearance. Their wings have upper surfaces that are brown, with orange and white markings, and blue eye spots. The latter are blue spots surrounded by a dark brown ring, which is in turn enclosed by an orange circle. There is a large eye spot at the outer margin of each fore wing, and two smaller eye spots on each hind wing. The front margin of each fore wing also bears a small blue bar bordered on each side by orange. Underneath, the fore wings have similar markings, against a pale brown background. The undersides of the hind wings are mottled brown with no distinct markings The butterflies have a wingspan up to 5 cms.
The butterflies are readily attracted to flowers where they are very easy to catch, and are often seen sunning themselves on the ground with their wings open. The butterfly is very hardy. It has been reported to winter in the Flinders Ranges (South Australia) during weather that was below freezing at nighttime.
