A wood-eating social insect — actually a derived cockroach — that builds elaborate colonies, decomposes vast quantities of plant matter, and causes billions in property damage annually.
A blood-feeding arachnid that transmits more diseases than any other arthropod — including Lyme disease, Rocky Mountain spotted fever, and rickettsial infections, with major populations expanding due to climate change.
Small, bell-shaped moths whose caterpillars are among the most damaging to gardens and orchards — they roll leaves into shelters bound with silk and eat the enclosed tissue; the codling moth (apple's worst enemy) and the light brown apple moth are tortrix moths, and European vine moth damages grapevines worldwide.
