This species was featured in News of the Week March 21, 2022:

Sexual dichromatism is the difference in color between males and females of the same species, and has been seen in several families of frogs. Palacios‑Rodríguez et al. (2022) explored the reproductive success of this phenomenon in Colostethus imbricolus, a cryptic poison dart frog that exhibits parental care. Unlike other dendrobatid frogs, tadpole transport in this species is predominantly performed by females, with more conspicuously patterned females transporting more tadpoles. In this instance of a sex-role reversal, the authors posit that males are assessing female fitness based on their coloration and that conspicous female coloration may serve as an aposematic signal for visual predators. This conspicuous coloration also is unique in that unlike other conspicuous females, C. imbricolus is not territorial. These findings highlight the varied reproductive strategies of amphibians and the complex evolutionary interactions of coloration, sexual selection, and antipredator strategies.
