E189: Why do treehoppers have such strange body shapes? [SJK Audio Edition]

About this episode

This episode explores how treehoppers use their unique body shapes to enhance their ability to sense electric fields in the air.

Abstract : Some animals can sense tiny electric fields around them. We call this electroreception. Sharks use it underwater. Using it in the air is harder, but some insects can do it. Treehoppers have strange body shapes with a part that can look like a helmet or crazy hat on their backs. We wanted to find out if this helps them use electroreception. We measured how much static electricity is on treehoppers, bees, and wasps. We then watched how treehoppers reacted to small electric fields – like the ones we measured on the insects. We also used computer models to test if their body shape made electric cues stronger around them. We found out that treehoppers, bees and wasps all produce electric fields. Wasps usually produce stronger electric fields than bees. Moreover, treehoppers can sense other insects’ electric fields. These fields can provide…
