What is the wingspan of Alcinoe Legionnaire butterflies?

Wingspans of 2.8 inches (7 centimeters) in males and 3.7 inches (9.5 centimeters) in females are characteristic of the Alcinoe Legionnaire (Acraea alcinoe) butterfly.

Specifically, the female is distinct from the female in both size and color. The female's forewings are much broader than the male's. Additionally, the male's orange-brown bands contrast markedly with the female's white.
