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
Conservation and restoration of insect specimens kind of documentation through digitization, bringing high quality images and associated information to anyone with access to the Internet. Large databases can hold vast amounts of information improving research efforts. Scientific illustration of insects is an older technique used to preserve information about collected insects. It visually documents insects, and unlike photography, can add intellectual ideas about anatomy and behavior of the insect through artists' renditions. Scientifically informed observation of specimens combined with technical and aesthetic skill yields the highly detailed illustrations necessary for the documentation of each species that is illustrated. This area of insect specimen documentation comes after
