insecto

Insecto is the Spanish term for insect, referring to members of the class Insecta within the phylum Arthropoda. In English-language biology, insects are described as the most diverse group of animals, with hundreds of thousands of described species and many more yet to be identified. In Spanish usage, the word “insecto” broadly covers all insects, while more precise classification may use taxonomic names or common species terms.

Key features of insects include a body divided into three parts — head, thorax, and abdomen — with three pairs of legs attached to the thorax. Most adults have one or two pairs of wings, though some species are wingless. Insects typically have one pair of antennae, compound eyes, and an exoskeleton made of chitin. Development often involves metamorphosis, which can be complete (egg, larva, pupa, adult) or incomplete (egg, nymph, adult).

Ecology and interactions with humans are diverse. Insects occupy a wide range of habitats and perform essential ecological roles such as pollination, decomposition, herbivory, and predation. They contribute to nutrient cycling and food webs, but some species also act as agricultural pests or vectors of disease. In scientific research, model organisms such as Drosophila melanogaster have roots in insect studies.

Evolution and diversity: insects display remarkably varied forms and life histories, with adaptations for flight, camouflage, and defense. The group’s success is tied to ecological versatility and rapid life cycles, which drive speciation and resilience in many environments.

Conservation: many insect populations face pressures from habitat loss, pesticides, and climate change. Preserving habitats and adopting integrated pest management are among common strategies to sustain their ecological roles.
