Cycads Use Infrared Heat to Attract Ancient Beetle Pollinators

12/12/2025

Summary

Story summary

A study published in Science shows cycads attract pollinators by generating infrared heat from their cones.
Researchers found beetles are drawn to the heated cones, which reach 15 to 27 degrees Fahrenheit above ambient air.
The study used 3D-printed cones to isolate infrared signals and confirmed beetles respond to infrared glow.
The findings imply an early form of pollination predating flowers, with heat reliance potentially limiting interactions with diverse insects.
