Mr.Bates observed that, when set out to dry, specimens of Heliconidae were less subject to the attacks of vermin; while both he and I noticed that they were not attacked by insect-eating birds or dragonflies, and that their wings were not found in the forest paths among the numerous wings of other butterflies whose bodies had been devoured.

Mr.Belt once observed a pair of birds capturing insects for their young; and although the Heliconidae swarmed in the vicinity, and from their slow flight could have been easily caught, not one was ever pursued, although other butterflies did not escape.

His tame monkey also, which would greedily munch up other butterflies, would never eat the Heliconidae.

It would sometimes smell them, but always rolled them up in its hand and then dropped them.
We have also some corresponding evidence as to the distastefulness of the Eastern Danaidae.
