The bee-flies {Bombylius) are also provided with a complicated sucking apparatus. (Fig. 15). In flying they carry their probosces forward and ready for action. They have the power of detecting concealed nectar in flowers in a most marked degree. Thrips enter all sorts of flowers, which they are enabled to do on account of their small size. They feed on both pollen and honey. (Figs. 12 and 13). Beetles in some cases show adaptations to utilize nectar and pollen, but there is a very marked difference in species and sub-orders. "None of our native plants," says Herman Mueller, -'are fertilized exclusively or mainly hy ; The large genus Meligethes, which are small insects and can creep into most flowers, is of much importance in pollinat- ing flowers. In flowers where the honey is exposed (Cornus,.
