Remarks about L.tarsalis from pages 260-261: "The type locality for this species is Ward, Colorado (Banks 1920), although it has rarely been collected in SPRB. Wissinger et al. (2003) suggested this species can complete their life cycle in ponds that dry up by early to mid-summer. Specimens were collected at elevations from 2177 m to 2813 m. Adults were present in July."

Quote from page 420: " In a study of fourteen tidepools along the north shore of the St Lawrence River, salinity levels again influenced the assemblages of insects found (Williams and Williams, 1976). In pools with a salinity, 2.5‰ there were caddisflies (Limnephilus tarsalis and Oecetis sp.), a dragonfly ( Aeshna interrupta), together with several species of beetle, corixid and chironomid. Whereas a few L. tarsalis were found in pools with salinity as high as 19.8‰, pools above 22‰ contained only the shore fly Ephydra subopaca and the marine midges Halocladius and Cricotopus sylvestris.
