Sat Apr 12 17:30:00 UTC 2025: ## Fruit Fly Larvae Join Elite Club of Electric Field Sensing Creatures
**SANTA BARBARA, CA – April 13, 2025** – Researchers at the University of California, Santa Barbara have made a surprising discovery: fruit fly larvae can sense and navigate using electric fields. This joins an exclusive group of animals, including sharks, bees, and platypuses, known to possess this ability.
The study, published April 12th, revealed that fruit fly larvae use a small cluster of sensory neurons located in their heads to detect negative electric potential. Experiments involved immersing the larvae in an electric field, observing their reorientation towards the negative electrode. Further investigation, using microscopy, pinpointed a single neuron within this cluster as the key receptor. This neuron’s activation or inhibition, depending on the electrode’s position, dictates the larva’s movement. The researchers meticulously ruled out other factors, confirming that the response was directly linked to the electric field itself.
This discovery sheds new light on the prevalence of electroreception in the animal kingdom and opens avenues for further research into the sensory mechanisms of insects.
