[6] The white eggs are found in clusters on the bottom side of Brunfelsia (Solanaceae).

[5] M. confusa as an instar has dark brown and yellow stripes transversely across the body.

[2] This species can be found in Brazil, Ecuador, Panama, Peru, Venezuela, Bolivia, Argentina, and Colombia.

[5] The population of M. confusa has been declining which could be due to the predation during the larval stage from ants and birds.
