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
National Fund for Scientific Research Auguste Piccard. The FNRS-1 was a balloon that set a world altitude record. The NFSR also funded the FNRS-2, which was the first ever bathyscaphe built. National Fund for Scientific Research The National Fund for Scientific Research (NFSR) (Dutch: NFWO, French: FNRS) was once a government institution in Belgium for supporting scientific research until it was split into two separate organizations: and The task of the FWO and F.R.S.–FNRS is to stimulate the development of new knowledge in all scientific disciplines. The means to achieve this, is to finance excellent scientists and research projects after an inter-University competition and with
