common name     Decorated Granite

Prairie badlands.

Alberta records are for late May and August, possibly indicating two broods.

Forewing uniform gray with a bold black AM and PM line and discal spot. Subterminal area shaded dark. Hindwing with faint discal spot and PM line. Very similar to the dark form of M. hebetata, but hebetata lacks the contrasting dark submarginal band distal to the PM line. Decorata also usually has a thin white area bordering the outer margin of the PM line of the hindwing, absent in hebetata.
