The insect known for having rasping-sucking mouthparts is Thrips. This unique adaptation allows them to feed on plant tissues effectively. Thrips possess mouthparts that are designed to pierce and scrape the outer tissue of plants, extracting juices. This feeding behavior can cause significant damage to a variety of crops, leading to wilting, discoloration, and stunted growth.

In contrast, other insects mentioned, such as bees, flies, and moths, have different types of mouthparts suited for their feeding habits. Bees primarily have a long proboscis for collecting nectar, which is a suction-based method suited for their diet of pollen and nectar. Flies typically possess sponging mouthparts that allow them to lap up liquids but do not have the rasping ability seen in thrips. Moths have a proboscis that coils to feed on nectar, which also does not involve the rasping-sucking method that is characteristic of thrips.
