About Marumba dyras Walker, 1856
Marumba dyras Walker, 1856 has a wingspan of 90–125 mm. Its body is pale brown, with a dark line that runs from the head to the end of the abdomen. On the forewing, there is a sub-basal line and three antemedial lines that converge toward the inner margin, plus two oblique, slightly bent post-medial lines, where the outer line is obsolescent. Another post-medial line curves from the costa to vein 2, then recurved upwards and inwards to enclose a red-brown spot that is surrounded by an indistinct line. Two curved sub-marginal lines are visible on the forewing. The hindwings are reddish brown and bear two red-brown spots. On the ventral surface of the forewings, lines are only present on the outer half. The ventral surface of the hindwing has two straight post-medial lines and two curved sub-marginal lines. The caterpillar is blue green with short white granular spines. It has lateral oblique streaks on the 5th to 10th somites, and a black-ringed white eyespot on the 4th somite. The caterpillar's horn is yellow. The pupa is dark red brown, and its spiracles and cremaster are black.
