How are different insects mouths adapted to eat in different ways?
Why do insects have different mouths? 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.
What do insects do with their mouths? All insects have their mouthparts on the outside of their heads, which are basically modified, paired appendages that are used to acquire and manipulate food. Insects with the siphoning type mouth, such as butterflies and moths, have a long proboscis that allows them to suck or siphon nectar and other liquids.
What adapts an insect for feeding? Some insects look like sticks, leaves, and thorns. This type of adaptation helps insect survive by blending in with their surroundings so they aren’t eaten or so that prey doesn’t see them hiding. Stink Bugs are the same color green as the leaves they like to eat.
