The Trichoptera include those insects which are popularly know as Caddis-flies and which are so dear to anglers, both in the larval and perfect stages of their existence. In their life-history, as well as in the general details of their structure, the caddis-flies bear a strong ressemblance to the dragon-flies, passing the earlier portion of their life beneath the surface of the water. Unlike those insects, however, they construct for themselves habitations, or cases in which to pass their larval existence, these differing in structure according to the species of the insect, and the nature of its surrounding.
