It is also worth pointing out that the common names used in the Bible refer only to color and broad morphological generalities shared by many Middle Eastern species. Also, although it is often useful for identification, the geographic location of these locusts in the text is unclear. Using primarily color to identify insect species is a notoriously unreliable approach. Insects that come to adulthood will have slightly different colors based on season, diet, and prevailing climate. Which species of locust are actually being referred to in the text is therefore nearly impossible to ascertain. This will further complicate adherence.
