Insect morphology least three different positions: prognathous, opisthognathous, and hypognathous. In species with prognathous articulation, the head is positioned vertically aligned with the body, such as species of Formicidae; while in a hypognathous type, the head is aligned horizontally adjacent to the body. An opisthognathous head is positioned diagonally, such as species of Blattodea and some Coleoptera. The mouthparts vary greatly between insects of different orders, but the two main functional groups are mandibulate and haustellate. Haustellate mouthparts are used for sucking liquids and can be further classified by the presence of stylets, which include piercing-sucking, sponging, and siphoning. The stylets are
Insect farming land use. This results in a tremendous amount of land-cover change which destroys local ecosystems and displaces people and wildlife. Insect farming is minimally space intensive compared to other conventional livestock, and can even take place in populated urban centers. Insect farming Insect farming is the practice of raising, eating, and breeding insects as livestock. Insects may be farmed for the commodities they produce, or for them themselves; to be used as food, as a dye, and otherwise. Silkworms, the caterpillars of the domestic silkmoth, are kept to produce silk, an elastic fiber made when they are in the process
