     Quote from page 570: "Limnephilus castor Ross and Merkley, 1952, was less common but found as recently as 2020, whereas the remaining endemic species were less common, patchily distributed, and not recently encountered. Hesperophylax consimilis (Banks, 1900) was recorded from only 3 lakes in Grand, Larimer, and Routt counties, of which the most recent was 28 years ago. Psychoronia costalis (Banks, 1901) was recorded at 5 high-elevation lakes (>3150 m) (see Fig. 2 and Supplementary Material 1), yet only within Boulder County and not since 1998. Grammotaulius lorettae Denning, 1941, was encountered only once from a lake in Larimer County in 1995 (Table 2, Supplementary Material 1)."
