Evolutionary mismatch can also be seen among insects. One such example is in the case of the Giant Jewel Beetle (Julodimorpha bakewelli). The male jewel beetle has evolved to be attracted to certain features of the female jewel beetle that allow the male jewel beetle to identify a female as it flies across the desert.[36] These features include size, color, and texture. However, these physical traits are seen manifested in beer bottles as well. As a result, male jewel beetles often consider beer bottles more attractive than female jewel beetles due to the beer bottle's large size and attractive coloring.[37] Beer bottles are often discarded by humans in the Australian desert that the jewel beetle thrives in, creating an environment where male jewel beetles prefer to mate with beer bottles instead of female jewel beetles. This is a situation that is extremely disadvantageous as it reduces the reproductive output of the jewel beetle as fewer beetles are mating. This condition can be considered an evolutionary mismatch, as a habit that evolved to aid in reproduction has become disadvantageous due to the littering of beer bottles, an anthropogenic cause.[38]
