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
Manipulator (insect) Manipulator (insect) Manipulator modificaputis is an extinct predatory cockroach which lived during the Upper Cretaceous period. The holotype specimen is fossilized in a 100-million-year-old piece of amber, which was found in a quarry of volcanoclastic mudstone (a sedimentary rock) at Noije Bum in the Hukawng Valley in Myanmar. The insect has been described by Peter Vršanský, of the Geological Institute SAS of Bratislava, and by Günter Bechly, of the Staatliches Museum für Naturkunde in Stuttgart. The cockroach was found to have an elongated neck, a freely rotating head and unexpectedly long legs, which are indicative of a predatory lifestyle. The
