Which insect group primarily feeds on starches and fabric?

The group of insects that primarily feeds on starches and fabric is moths. This is particularly true for the clothes moth, which is known for damaging fabrics made from animal fibers, such as wool, silk, and fur, as well as items containing starch, like those with food residues. Moths possess specialized mouthparts that allow them to chew and ingest these materials, leading to substantial damage in infested items.

In the context of pest control, understanding the feeding habits of moths is vital for effective management strategies. For instance, thorough cleaning of textiles and careful storage can help eliminate food sources for moth larvae, thus preventing infestations.

While other insects listed might have their own unique feeding habits, they do not primarily target starches or fabric. Fleas, for instance, are more associated with feeding on the blood of mammals, termites primarily consume wood and cellulose, and sucking lice feed on the blood of their hosts, primarily humans or animals. Moths' specific diet makes them well recognized as pests in homes that store fabrics, clothing, and other items containing starches, which highlights their significance in structural pest control practices.
