Which of the following characteristics most likely explains why insects are so successful?

Insects are renowned for their success and diversity, which can be largely attributed to their ability to fly, a characteristic provided by wings. This remarkable adaptation allows them to escape predators, find food, and colonize a variety of habitats. The ability to fly also facilitates migration and dispersal, enabling insects to quickly exploit new environments and resources.

Wings have propelled insects into numerous ecological niches, making them one of the most abundant groups of organisms on the planet. This adaptability is a key factor in their evolutionary success, allowing them not only to survive but to thrive in diverse ecosystems worldwide.

While traits like internal fertilization, jointed appendages, and chewing mandibles contribute to the overall success and adaptability of insects, it is the evolution of wings that stands out as a pivotal characteristic for mobility and survival in a wide range of environments.
