• Sexes are separate.
• Fertilization is usually internal.
• Insects usually lay a great many eggs. 
• Insects as all animals have various means of attracting mates. Segregate pheromones, to use flashes of light, produce sounds or color signals; those are various kinds of courtship behavior.
• The reproductive system consists of the testes in the male and the ovaries in the female, together with ducts that carry their products to a sexual opening close to the anus.
