Why do insects have different mouth parts?
As insects evolved to feed on a wider variety of food resources, their mouthparts adapted accordingly through natural selection. In some cases, an individual component of the mouthparts became specialized for a new function. In weevils, for example, the front of the head is elongated into a long, slender proboscis.
