Red leaves on a trail usually mean that there are leaf cutter ants carrying dinner to their den. The ants do not actually eat the leaves. They feed the leaves to a fungus and eat the fungus.
The ants know what type of leaves the fungus prefers. The red leaves may be an attractive color for humans, but I assume that the fungus cares only about taste, and not about the presentation of the meal. After all, the fungus is not only color blind, it does not have any eyes.
This week we are showing photos of Antigua, Guatemala on our Viva la Voyage travel photo site.
