Structures of Gall-Flies and Apliidcs. Many of the jirocesses which we have detailedbear some resemblance to our own operations ofbuilding with materials cemented together; but weshall now turn our attention to a class of insect-architects, who cannot, so far as we know, be matchedin prospective skill, by any of the higher orders ofanimals. We refer to the numerous family whichhave received the name of gall-flies,—a familywhich, as yet is very imperfectly understood, theireconomy being no less difficult to trace, than theirspecies is to arrange in the established systems ofclassification.

GALL-FLIES. 371 stances of the nests constructed by gall-insects, maybe found in abundance during the summer, on theleaves of the rose-tree, the oak, the poplar, the wil-low (Salix vimmalis,) and many other trees, in theglobular form of a berry, about the size of a currant,and usually of a green colour, tinged with red, likea ripe Alban or Baltimore apple. When this pseudo apple in miniature is cut into,it is found to be fresh, firm, juicy, and hollow in thecentre, where there is either an egg or a grub safelylodged, and protected from all ordinary this hollow ball the egg is hatched, and thegrub feeds securely on its substance, till it preparesfor its winter sleep, before changing into a gall-fly(Cynijjs), in the ensuing summer.
