Social insects such as bees, ants, and termites show cooperation, division of labor, and communication. These traits allow colonies to function as highly organized units.

Most insects use internal fertilization. This protects gametes from drying and supports reproduction in terrestrial environments.

Egg maturation involves growth of the oocyte, yolk deposition, and formation of protective egg coverings. These processes support early embryonic development.

Mechanoreceptors detect physical forces such as touch, vibration, stretch, or air movement. Sensory hairs and chordotonal organs are common insect examples.

Pheromones are chemical messages released by one individual and detected by another. They can guide mating, alarm behavior, trail following, or aggregation.

Juvenile hormone influences developmental outcome. High levels tend to maintain juvenile characteristics, while low levels permit adult differentiation during metamorphosis.

Holometabolous insects often reduce intraspecific competition because larvae and adults differ in form, food, and habitat. This helps explain their evolutionary success.
