[1][2] The species was originally described by Leonard Gyllenhaal in 1836.

[3] Eurhinus magnificus is brilliantly coloured.

Its host plant is Cissus verticillata.

[4][5] Early descriptions from 1909 indicate that Eurhinus magnificus does not extend south of Nicaragua,[1] however observations aggregated in GBIF suggest that the species moved more south towards Panama.

The species might have been introduced to Florida through banana shipments from Costa Rica.
