Insects such as ants and bees also have their own unique "small society". These insects will determine which sex is more "useful" for the group, and then determine "giving a male" or "giving a female". This is a project of the University of Oxford in the United Kingdom. The latest research findings. By studying the internal division of labor and reproductive methods of ants and other insect groups, it is found that these insects will control the ratio of male to male according to the actual role of different sexes in the group. For ordinary ants, female ants are often responsible for the main work in the group, males The role is relatively small, so it will actively multiply female offspring. The "workload" of male and female in termite colony is equivalent, so the number is basically close. Ants, bees and other insects can actively control whether to fertilize eggs to control offspring when they are fertile The fertilized egg will develop into a female, and the unfertilized egg will develop into a male. Insects that live in the air are mostly active during the day. The adult stage has developed wings, usually with developed mouth parts, and the adult has a longer life span. Such as bees , Wasps, dragonflies, flies, mosquitoes, gadfly, butterflies, etc. Insects in the aerial stage are mainly for migration and spreading, hunting for food, mating and courting and choosing spawning places.
