Direction and strength of selection by predators for the color of the aposematic wood tiger moth by Lindstedt, C., Eager, H., Ihalainen, E., Kahilainen, A., Stevens, M., Mappes, J.

Hairiness and warning colours as components of antipredator defence: additive or interactive benefits? by Lindstedt, C., Lindström, L., Mappes, J.

“…To deter predator attack, aposematic prey species advertise their unprofitability with one or more conspicuous warning signals that, in turn, enhance the…”
