Meadow Argus

Fascinating facts about the Meadow Argus

• The meadow argus sports two brownish wings each bearing a pair of striking black and blue eyespots surrounded by white and orange edging. These eyespots serve a dual defensive role: they startle potential attackers and act as visual decoys that draw bites away from vital wing tissue. When a predator strikes the conspicuous markings, the butterfly often loses only a tiny fragment of wing rather than a fatal injury.
• When the meadow argus settles it can assume four distinct postures that shift with light levels and perceived danger. In bright sunshine it simply opens and relaxes its wings, while an approaching threat in the same light prompts it to spread the wings further, flashing the hind-wing eyespots. In shade the butterfly folds its wings closed, but if danger looms it raises its forewings to reveal hidden spots on the underside.
• In the late summer of 1886 an extraordinary drift carried thousands of meadow argus butterflies across the Tasman Sea into New Zealand, creating a brief surge of the species there. Although that historic influx is well recorded, the butterfly is now a rare sight on the islands, with only occasional records.
• Each year in the southern hemisphere spring the meadow argus undertakes a northward journey, leaving its southern Australian range for milder climates. This movement occurs specifically in October or November, timing the flight to avoid the approaching winter chill. By heading to warmer habitats the butterflies ensure access to suitable food plants and breeding sites during the colder months.
• Male meadow argus butterflies have a wingspan of four centimetres, while females are slightly larger at four point three centimetres, a modest sexual size difference. These measurements correspond to about 1.6 inches for males and 1.7 inches for females, indicating a subtle dimorphism that can aid identification in the field. The size is typical for the species, whose brownish wings carry distinctive eyespots used for defence.
