General DescriptionA fairly large (5.0 - 6.2 cm wingspan) brownish grey moth with darker markings. The forewings are grey with darker lines and spots, and with the veins lightly lined with dark scales. The postmedian line is doubled and the interspace is white, forming a contrasting toothed band. The hindwing is pale grey-brown with a faint darker median line and veins in the male. The female is similar but darker, especially the hindwings which are sooty brown. The antennae of both sexes are simple. A. dactylina is similar, but is lighter powdery grey, with fewer markings and in particular lacking the doubled, white-filled postmedian band on the forewing, the median line on the hindwings, and the dark scales along the veins.
