Insect cooking oil, insect butter and fatty alcohols can be made from such insects as the superworm (Zophobas morio). [199] Insect species including the black soldier fly or the housefly in their maggot forms, and beetle larvae such as mealworms , can be processed and used as feed for farmed animals including chicken, fish and pigs.

Meganeura is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). It is a member of the extinct order Meganisoptera, which are closely related to and resemble dragonflies and damselflies (with dragonflies, damselflies and meganisopterans being part of the broader group Odonatoptera).
The insects' margins are usually light brown or yellow with a metallic green or brown underside. The insect is typically ¾-1.5 inches in length. Compared to the legs of a common June beetle, the legs are shorter, and the body is stouter.
In these insects, the testes are tubular and the first abdominal sternum (a plate of the exoskeleton) is divided by the hind coxae (the basal joints of the beetle's legs). [49] Archostemata contains four families of mainly wood-eating beetles, including reticulated beetles (Cupedidae) and the telephone-pole beetle . [ 50 ]
Miniature sensors, a computer chip, and a solar panel were fitted in a "backpack" over the insect's thorax in front of its wings. Light is sent down flexible light-pipes named optrodes [c] from the backpack into the nerve cord to give steering commands to the insect. The result is a "micro-aerial vehicle that's smaller, lighter and stealthier ...
As in all insects, the body is divided into three sections: the head, thorax, and abdomen. The thorax is composed of three segments, each with a pair of legs. In most families of butterfly the antennae are clubbed, unlike those of moths which may be threadlike or feathery. The long proboscis can be coiled when not in use for sipping nectar from ...
Some dipteran larvae are leaf-miners. The larvae of many brachyceran families are predaceous. In many dipteran groups, swarming is a feature of adult life, with clouds of insects gathering in certain locations; these insects are mostly males, and the swarm may serve the purpose of making their location more visible to females.

Among the many aquatic insects that catch mosquito larvae are dragonfly and damselfly nymphs, whirligig beetles, and water striders. Vertebrate predators include fish such as catfish and the mosquitofish, amphibians including the spadefoot toad and the giant tree frog, freshwater turtles such as the red-eared slider, and birds such as ducks.
