A pair of mating D. femorata in the Hudson Highlands region of New York. The common walkingstick is a slender, elongated insect that camouflages itself by resembling a twig. . The sexes differ, with the male usually being brown and about 75 mm (3 in) in length while the female is greenish-brown, and rather larger at 95 mm (3.7 i
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.

Like other species of wheel bugs, A. cristatus have a characteristic dorsal crest, shaped like a wheel or cog. [10] They move and fly slowly, and in flight produce a noisy buzzing sound. As with other assassin bugs, the proboscis arises from the anterior end of its long, tubular head and unfolds forward when feeding. [citation needed]
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
[47] [48] [49] A 2009 metastudy by Hodek and Honěk found that aphid-eaters constituted around 68 percent of species that live in temperate areas but only 20 percent of species worldwide. Around 36 percent of total species mostly feed on scale insects. [49] Larvae and adults eat the same foods, unlike in other insect groups. [7]
Mayflies have ancestral traits that were probably present in the first flying insects, such as long tails and wings that do not fold flat over the abdomen. Their immature stages are aquatic fresh water forms (called "naiads" or " nymphs "), whose presence indicates a clean, unpolluted and highly oxygenated aquatic environment.
The pupa is a tough capsule from which the adult emerges when ready to do so; flies mostly have short lives as adults. Diptera is one of the major insect orders and of considerable ecological and human importance. Flies are major pollinators, second only to the bees and their Hymenopteran relatives.
Insects are the most diverse group of Arctic animals (about 3,300species), of which about 50% are Diptera. Palearctic habitats include meadows, prairies, mountain passes, forests, desert oases, seashores, sandy beaches, coastal lagoons, lakes, streams and rivers, bogs, fens, areas (including waters polluted by rotting waste, industrial ...
