Natural history of insects : comprising their architecture, transformations, senses, food, habits--collection, preservation and arrangement . asthe hawthorn, the elm, the oak, and most fruit-treesparticularly the pear, form habitations which areexceedingly ingenious and elegant. They are sovery minute that they require close inspection todiscover them; and to the cursory observer, unac-quainted with their habits, they will appear more likethe withered leaf scales of the tree, thrown off whenthe buds expand, than artificial structures made byinsects. It is only, indeed, by seeing them moveabout upon the leaves, that we discover they are in-habited by a hving tenant, who carries them as thesnail does its shell. These tents are from a quarter of an inch to aninch in length, and usually about the breadth of anoat-straw. That they are of the colour of a withered 224 INSECT ARCHITECTURE. leaf is not surprising; for they are actually composedof a piece of leaf; not, however, cut out from thewhole thiclaiess, but artfully separated from theupper layer, as a person might separate one of theleaves of paper from a sheet of pasteboard..

The tents of this class of caterpillars, which arefound on the elm, the alder, and other trees with ser-rated leaves, are much in the shape of a minutegold-fish. They are convex on the back, where theindentations of the leaf out of which they havebeen cut add to the resemblance, by appearuig likethe dorsal fins of the fish. By depriving one of thosecaterpillars common on the hawthorn of its tent, for the sake of experiment, we put it under the ne-cessity of making another; for, as Phny remarks ofthe clothes-moth, they will rather die of hunger thanfeed unprotected. When we placed it on a freshhawthorn leaf, it repeatedly examined every part ofit, as if seeking for its lost tent, though, when thiswas put in its way, it wou
