Os coleópteros (Coleoptera) compõem uma ordem muito diversa de insetos, entre os quais os mais populares são os besouros e as joaninhas. No entanto, essa ordem compreende também escaravelhos, gorgulhos entre outros. “Coleoptera” é uma palavra de origem grega, unindo koleos (estojo) e pteron (asas) que, em tradução livre, significa ‘estojo de asa’. Esse nome é explicado através da morfologia desses animais: o par de asas anteriores (externo) é esclerotizado e funciona como uma capa rígida, conhecida como élitro, visando proteção. O outro par de asas, posteriores e internas às asas rígidas, é mais delicado, membranoso, e serve para voar. A ordem Coleoptera possui o maior número de espécies dentre todos os seres vivos — em torno de 350 mil — sendo portanto o grupo animal que possui maior diversidade. Coleópteros estão presentes em uma imensa variedade de habitats todos os ambientes da Terra, à exceção do oceano, onde têm presença mínima, embora eles ocorram em muitos litorais. Uma característica que teria contribuído para o sucesso da ordem seriam os élitros (ver seção morfologia), protegendo o par de asas com função de voo quando este não está em uso, e permitindo que estes animais ocupassem, como citado, os mais diversos ambientes. Além da megadiversidade, a ordem Coleoptera apresenta grande variedade morfológica a depender do modo de vida de cada espécie.
Coleoptera (Coleoptera) make up a very diverse order of insects, among which the most popular are beetles and ladybugs. However, this order also includes beetles, weevils and others. “Coleoptera” is a word of Greek origin, uniting koleos (case) and pteron (wings) which, in free translation, means ‘wing case’. This name is explained through the morphology of these animals: the pair of anterior (external) wings is sclerotized and functions as a rigid cap, known as elitro, for protection. The other pair of wings, posterior and internal to the rigid wings, is more delicate, membranous, and serves to fly. The order Coleoptera has the largest number of species among all living beings - around 350 thousand - and is therefore the animal group that has the greatest diversity. Coleoptera are present in an immense variety of habitats in all environments on Earth, with the exception of the ocean, where they have minimal presence, although they occur on many coasts. A characteristic that would have contributed to the order's success would be the elites (see morphology section), protecting the pair of wings with flight function when it is not in use, and allowing these animals to occupy, as mentioned, the most diverse environments. In addition to the megadiversity, the order Coleoptera presents a great morphological variety depending on the way of life of each species.
