Which type of insect is a longhorned beetle classified as?

A longhorned beetle is classified as belonging to the order Coleoptera. This order is characterized by insects that possess hardened forewings called elytra, which protect their delicate hind wings and bodies. Coleoptera is the largest order of insects, encompassing a vast diversity of beetle species, including longhorned beetles that are known for their distinctly long antennae, which can be as long as or longer than their bodies. These unique features allow longhorned beetles to be easily identified within the Coleoptera order, highlighting their specific adaptations and ecological roles.

The other options represent different insect orders with unique characteristics that do not include longhorned beetles. Lepidoptera consists of butterflies and moths, known for their scaled wings; Ephemeroptera includes mayflies, characterized by their short adult lifespan; and Neuroptera contains lacewings and antlions, which typically have net-veined wings. Each of these orders bears distinct morphological and behavioral traits that differentiate them from beetles.
