Humans see things from their own perspective. When we see a shiny, iridescent beetle, it stands out. Our logic says, “sitting duck!” To test this assumption, entomologists used the elytra (wing cases) of different beetles and attached a mealworm larvae. If hungry birds saw the wing cases they would tend to eat the mealworms that stood out. The iridescent ones should have been eaten first. Instead, all the other colors were eaten before the iridescent ones. Whether birds cannot see these or are warned away is unknown. One thing is for sure, iridescence will save you in the forest!
