Micro Caddis inhabit the bottoms of clear lakes, streams and rivers throughout hilly and mountainous regions of North America, excluding the extreme southeast.  The tiny larva are net-spinning and case-building types:  some build flat shelters shaped like silken coins attached to rocks; others can look like a collection of quonset huts.  Pupa seal themselves in potato-shaped protective cases.  Spring to late summer emergence.
