Now, an international zoology team has discovered that some insect species can manage to see what their relatives cannot.
“To our knowledge, we are the first to have experimentally demonstrated that beetles can actually perceive the color red,” said Johnnes Spaethe, paper co-author and chair of zoology at Germany’s University of Würzburg.
The team utilized a number of methods to determine the two beetles weren’t traveling to the red flowers simply due to a UV sensory situation similar to bees.
Aside from UV light, the bugs are able to process blues, greens, and deep reds—although field observations indicated the insects used true color vision to identify and visit red flowers.
This suggests the ability to see red—as well as nature’s many other colors—may be relatively more malleable than previously thought.
