Intra-species recognition systems are often subtle. For example, ornithologists have great difficulty in distinguishing the chiffchaff from the willow warbler by eye, and there is no evidence that the birds themselves can do so other than by the different songs of the male. Sometimes, intra-species recognition is fallible: in many species of frog, the males are commonly seen copulating with females of the wrong species or even with inanimate objects.
Heliconius charithonia displays intra-species recognition by roosting with conspecifics. They do this with the help of UV rhodopsins in the eye that help them distinguish between ultraviolet yellow pigments and regular yellow pigments.[1] They have also been known to emit chemical cues in order to recognize members of their own species.[2]
