Bark Beetle Comparison

Why does “gestalt” identification works with some bark beetles? Species of the genus Diuncus from Papua New Guinea, for example, differ in characters that are difficult to code as discrete, but anybody with one of these specimens in hand could immediately tell the species by its shape and color if the whole diversity were laid out as in this example. A new mobile app developed by entomologists at the Forest Entomology lab at the University of Florida and the U.S. Department of Agriculture-Agricultural Research Service’s Systematic Entomology Laboratory aims to train users in bark beetle identification.
