What insects produce mucus?

Certain insects, such as caterpillars and some species of termites, produce mucus as part of their biological processes. Caterpillars secrete mucus to aid in movement and to protect themselves from predators. Termites use mucus to help construct their nests and to bind materials together. Additionally, certain aphids produce a sticky substance that can resemble mucus, which helps in creating a protective coating for themselves and their colonies.
