Cicadas, those buzzing insects that emerge every few years, are fascinating creatures with a unique life cycle. But did you know that color can play a role in their behavior, particularly when it comes to attraction? While cicadas aren’t as visually oriented as some other insects, research suggests that they might have certain color preferences.

Do Colors Really Matter to Cicadas?
Unlike bees that are drawn to bright, vibrant hues, cicadas primarily rely on sound for communication and mating. Their loud, buzzing calls serve as their main method of attracting mates. However, studies have shown that cicadas are not entirely colorblind. They have visual receptors that allow them to perceive certain wavelengths of light.
What Colors Might Attract Cicadas?
While more research is needed to definitively say which colors attract or repel cicadas, there’s some evidence suggesting that they might be more attracted to:
- Yellow and Green: These colors are often associated with vegetation, which could be why cicadas might find them appealing.
- Light Colors: Some studies suggest that cicadas might be more likely to land on lighter-colored surfaces.
Why Do Cicadas Seem Attracted to Certain Objects?
You might have heard anecdotes of cicadas swarming cars or landing on people wearing specific colors. While color might play a minor role, these behaviors are likely due to a combination of factors, including:
- Heat: Cicadas are cold-blooded and attracted to warmth. Darker surfaces absorb more heat, which might explain why they seem drawn to certain objects.
- Vibration: Cicadas are highly sensitive to vibrations. The vibrations from machinery or even human activity could potentially attract them.
- Mating Season: During peak mating season, cicadas are more active and might exhibit seemingly unusual behaviors as they search for mates.
Keeping Cicadas at Bay
If you’re concerned about cicadas during their emergence, there are a few things you can do:
- Avoid Wearing Bright Yellow or Green: While the evidence is inconclusive, it might be best to avoid these colors during cicada season, just in case.
- Park Cars in Shaded Areas: This can help reduce the heat buildup that might attract cicadas.
- Use Insect Repellent: Insect repellents designed for flying insects might deter cicadas.
Conclusion
While the role of color in cicada attraction is still being studied, it’s clear that their primary senses for communication and mate selection are sound and vibration. However, their ability to perceive certain colors adds another layer of complexity to their fascinating world. By understanding their behaviors, we can appreciate these noisy summer visitors and coexist with them during their brief time above ground.
