An insect known as the pigeon horntail (Tremex columba) deposits its eggs, by means of a strong, piercing ovipositor, half an inch deep in the trunk wood of growing trees. Female uses ovipositor to bore through bark into wood, depositing 1 slender egg in each hole. Eggs are covered with fungal spores from a special pocket in female's abdomen. After depositing the last egg, the female often dies without removing its ovipositor from the wood. The dead female becomes food for some insectivorous animal.

The Puss Moth (Cerura vinula) is a lepidoptera from the family Notodontidae. The puss moth is stinging caterpillar, Megalopyge opercularis, commonly called an asp. This is one of the most toxic caterpillars in North America. The mature larva is 1 to 1½ inches long with seven pairs of prolegs (suction-cup like claspers on the rear of the body). This larva of the puss moth shows as it appears when undisturbed.

Most scale insects are parasites of plants, feeding on sap drawn directly from the plant's vascular system. Male scale insects are unusual in possessing only one pair of wings, thus making them resemble true flies (Diptera), though they lack the halteres (rudimentary hind wings) seen in flies, and have tail filaments, which do not occur in flies.
