Bates's original work was done on a group of conspicuous butterflies always spelled by Bates as ''Heliconidae''. He divided this assemblage into two groups, the ''Danaoid Heliconids'', having affinities with the tribe [[Danaini]] (see also [[Danainae]]); and the ''Acraeoid Heliconids'' related to the [[Acraeini]]. The former are now known as [[Ithomiini]], closely related to the milkweed butterflies, and were named after the genus ''[[Danaus]]'' in the [[Danainae]]. The latter are now known as the [[Tribe (biology)|tribe]] [[Heliconiini]], or longwings, named after the genus ''[[Heliconius]]''. Both group within the family [[Nymphalidae]], and both groups tend to feed on poisonous plants. The [[milkweed]] plant supplies poisonous glycosides which render both caterpillar and adult danaines noxious. Ithomiines, in contrast gain their toxicity from their adult nectar sources.  Heliconiine caterpillars feed on poisonous ''[[Passiflora]]'' vines. However, ithomiines gain their toxicity from their adult food plants.
