Herbivores:
This information is based an ongoing project dedicated to the inventory and dissemination of information on lepidopteran larvae, their host plants, and their parasitoids in a Costa Rican tropical wet forest and an Ecuadorian montane cloud forest.
N=28 herbivore associations as of 2012.
Erebidae: Bertholdia partita (Rawlins); N=1, Unknown spp.; N=12.
Hesperiidae: Unknown spp.; N=3.
Nymphalidae: Pteronymia sp.; N=1.
Caterpillars from several other families that were collected all failed to pupate. This suggests that they may not in fact feed on R. fragilis.
Larval lepidopteran herbivores reared in Napo Province, Ecuador (Yanayacu Biological Station and Center or Creative Studies).
