Here is a direct proof that something morethan cold and absence of food is required to determine thefirst metamorphosis of the Lcpidoptera, and that it cannot takeplace until the development of the caterpillar has advanced to CURIOSITIES OF METAMORPHOSIS. 157 a certain and definite stage—that stage being determined byhereditary pecuHarities, The metamorphoses of the Hydrocaiiipida^ are very interesting,on account of the extraordinary change which occurs in the con-dition of hfe between a swimming larva and a gay moth, to whichwater is almost certain death. The examples of the correspondingtransformations of the gaily-coloured flies that lead aquatic exis-tences in the larva state naturally rise up before us, as also dothe Zoca of the crustaceans, and all these peculiarly allied formsbecome more strongly than ever united in a common
