Abstract: | The structure and function of the forelimbs of praying mantids are discussed. A large spine on the femur and the spine on the end of the tibia were shown experimentally to be important in the capture of unrestrained flies. These spines may function to narrow the gap through which a fly may escape while the tibia is closing on the femur. Some of the spines on the femur are hinged at their base; the structure, properties and possible functions of these spines are discussed. Similar hinged spines are reported on the lorelimbs of Stomatopoda (CrustaceaI but were not found in the Mantispidac (Neuroptera:Insecta). The variation of forelimb structure within the Mantodea is briefly discussed. The theory that the optimum prev size can be predicted from the geometry of the mantid forelimb is critically discussed. |
