Blue-banded Eggfly

The adult male butterflies are black on top, with a blue band across each wing, and a double row of subterminal pale spots. Underneath, the males are brown with a smoky pale band across each wing, and a subtermial row of pale spots, and pale edges.
The females have an extra white flash or row of white spots across the tip of each forewing. The undersides of the females are similar to their upper surfaces.
