Bioluminescent fungi attract insects like click beetles with their glow. When insects land on the glowing fungi, they pick up spores and later drop them in new locations, helping the fungi to grow in different areas.

Bioluminescent fungi attract insects like click beetles with their glow. When insects land on the glowing fungi, they pick up spores and later drop them in new locations, helping the fungi to grow in different areas.  The insects are drawn to the light for various reasons, such as seeking mates or food, but it's the fungi that mainly benefit from this interaction by enhancing their spore dispersal.
