Scientists Find Crickets Nurse Sore Antennae Like Dogs

Scientists just watched crickets do something surprisingly familiar: nurse their injuries exactly like your dog licks a sore paw.

Researchers at the University of Sydney discovered that house crickets stroke and groom a hurt antenna over extended periods, showing what scientists call "flexible self-protection." It's the same behavior we'd instantly recognize as pain in our pets.

Associate Professor Thomas White and his team had to give crickets a gentle "ouchy" to test their theory. They randomly selected crickets to receive a brief touch from a 65-degree soldering iron on one antenna—hot enough to be unpleasant but causing no lasting harm.

The crickets that got the hot probe overwhelmingly focused on their affected antenna. They groomed it more frequently and tended to it over longer stretches of time.

The other crickets, who received an unheated probe or no treatment at all, got a bit flustered but quickly resumed normal activities. The difference was striking.

"They weren't just agitated and flustered," White explains. "They were directing their attention to the actual antennae that was hit with this hot probe."

The finding joins growing evidence that insects have complex inner lives. Recent studies show bumblebees play with colored wooden balls for fun, and stressed bees display pessimistic behavior.

Over 500 leading scientists signed the New York Declaration on Animal Consciousness, acknowledging a "realistic possibility of conscious experience" in insects. Some countries already recognize sentience in cephalopods and crustaceans—and insects may be next.

Why This Inspires

This research asks us to look past our differences and extend empathy to creatures that seem nothing like us. Bogong moths navigate hundreds of kilometers at night to places they've never been. Insects make complex decisions, learn from experience, and now appear capable of experiencing pain.

"These aren't just little machines," White says. "They have rich capabilities to learn, to make complex decisions and trade-offs."

The stakes are particularly high for crickets, who are farmed in the billions and trillions for food, feed, and research—the chickens and cows of the insect world. If they're capable of having better and worse lives, perhaps we owe them consideration.

Associate Professor Kate Umbers from Western Sydney University, who wasn't involved in the study, says people underestimate insects "all the time." Humans struggle to appreciate things different from themselves.

Her hope? That this study inspires us to embrace the empathy we naturally feel toward other living things, no matter how many legs they have or how small they are.

The research challenges us to think more carefully about how we interact with the tiniest creatures sharing our world—and maybe think twice before reaching for that bug spray.
