Macrosoma cascaria is moth-like butterfly described by William Schaus in 1901.

[2] The species is found in Mexico: Xalapa, Tabasco and Misantla near the coast north of Veracruz to the northern Venezuela.

[3] The male genitalia are extremely similar to those of M. albifascia, but the chestnut apical patch in M. cascaria and the absence of the broad white forewing band make the two species easy to distinguish.

The colour pattern is most closely resembles to that of M. paularia, but M. cascaria differs in having the white, costal patch and darker hindwings.

The shape of the Gnathos also differs in having the medial element downcurved.
