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 Habitat before its offspring's eggs were ready to be segregated. Insect Habitat The Insect Habitat was a science payload intended for the International Space Station as part of the Space Station Biological Research Program (SSBRP). The project was put on hold when Space Shuttle flights were interrupted after the destruction of Orbiter Columbia in February 2003. The insect research element of the program was managed by the Canadian Space Agency, and the prime contractor for the Insect Habitat was Routes AstroEngineering, of Ottawa, Ontario. The Insect Habitat would enable studies of the fruit fly to learn how microgravity affects development, nervous
