An Ability to Fly (Class Pterygota): Because certain insects evolved wings, they were able to quickly flee predators and travel long distances without encountering any risk from other creatures in the air. The early insects were most likely wingless. This implies that flight was and continues to be a natural selection advantage for many insect species.

Small Structure: If small-stature insects expanded to an unnatural size, they would have breathing problems. As a result, a large range of insect species are tiny in size, allowing them to occupy small spaces and requiring only a minimal amount of food to thrive.

Fast Reproductive Cycle: According to biology, smaller species create children faster, according to science, and because organisms at the time reproduced sexually, this meant that genetic information was crossing more frequently. As a result, the variety in the genome of the species as a whole grew, and the species continued to diversify and compete.

Land Insects: They, like the other arthropods, took advantage of the opportunity to live on dry land and developed to fit their new surroundings. The minimal water transpired by insect species has been traced out through evolutionary adaptations, demonstrating their relatively bold shift from a moist habitat to dry ground. The water is also home to insects. They were, however, up against greater competition from the ongoing development of other species in the area. This resulted in environmental pressure and a habitat occupancy threshold.

Senses: Insects continued to develop the senses that other arthropods and their predecessors had evolved. They were able to recognize and understand auditory, visual, and chemical inputs.
