Ants live in large groups and eat plants and insects. The queen ant lays all the eggs. Flying ants only fly when warm and humid. Woodlice are crustaceans, not insects. They eat decaying plant matter and live in damp places. When threatened, they roll into a ball. Stag beetles are the largest British insect. They live mainly in rotten wood. The larvae live for 3-5 years while the adult only lives from May to August. They eat small insects. Worms are hermaphrodites and eat decaying plants. They add air to soil and do not have bones. Spiders produce webs to catch prey like flies
