The evolution of the wasp waist, a constriction between the first and the second abdominal segment greatly improving the maneuverability of the abdomen's rear section, including the ovipositor, was a major innovation in the evolution of hymenoptera that undoubtedly contributed to the rapid diversification of apocrita (n5. Australian native wasps are the most visual they often hunt by sight some wasp species have larvae that eat plants the same way that caterpillars do. The evolution of complex molecular systems can occur in several ways natural selection can bring together parts of a system for one function at one time and then, at a later time, recombine those parts with other systems of components to produce a system that has a different function.

  • There is evidence that the reflectance spectra of many flowers target the distinctive visual discrimination abilities of hymenopteran insects, but far less is known about bird-pollinated flowers birds are hypothesized to exert different selective pressures on floral colour compared with hymenopterans because of differences in their visual systems.
  • In the visual systems of honeybees and blue tits, the peak spectral absorbance of their photoreceptors lies in different regions of the spectrum for example, honeybees are maximally sensitive to uv at 344 nm ( menzel and backhaus, 1991 ), while the uvs cone of blue tits is maximally sensitive at 375 nm ( hart, 2001 .
