Camouflage vs Warning Colors: Insect Defense Strategies
The effectiveness of camouflage or warning colors for insect defense depends on various conditions, including light levels and predator presence.
Prey animals can use their colors to either hide from predators or dissuade them from attacking, but local conditions determine which option works best.
“This is the most comprehensive experimental study on warning signal success that I have ever seen,”
says David Kikuchi, an evolutionary biologist at Oregon State University.
A global study published in Science on September 25 reveals that camouflage and warning colors each excel under certain environmental conditions.
The findings identify fundamental factors driving the evolution of both strategies worldwide.
Author's summary: Camouflage and warning colors have different effectiveness.
- Camouflage is effective in certain conditions.
- Warning colors are effective in other conditions.
