When not feeding they rest upon the twigs; in such a manner as enables them to very frequently escape detection. Two speeies, C* Parta, Guen., and C. Concumbens, Walk., are recorded from willows. Fig. 29 shows Catocala Ultronia, Hubn., a species which is sometimes found upon plum, as mentioned by Prof. Saunders in his " Insects Injurious to ;. Fig. 29. The last division of the Macro-Lepidoptera (or larger forms) is the Geometridse, the larvae of which are the " loopers " or " measuring worms," so well known, and several of which are occasionally found upon willows. Among the Micro-Lepidoptera—those minute species (such as the Clothes Moth) which are so numerous and so difficult to distinguish, except by entomologists who have specially studied them—there are many species feeding in or upon the galls produced by other insects, or in mines made in the leaves. When leaves are examined they will often be found to have white blotches upon them, or to be traversed by serpentine white streaks. Closer examination will show that these are internal injuries, produced by the eating away of the inner tissues of the leaf. The minute flattened larvae will be often found in their burrows, and can be watched in their work of destruction. The habits of these small motbs are of interest, but cannot be dwelt upon Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Entomological Society of Ontario; Ontario.
