Limnephilus tarsalis (Banks) (I) Nearctic, western Distribution: Yukon, Alaska, Northwest Territories, Alberta, British Columbia, Wyoming, Colorado. Yukon records: 10 (ROME). Biological information: Adults have been collected in the Yukon 27 July. Taxonomic notes: L. alvatus Denning is a junior synonym (Ruiter 1995). Genus Nemotaulius. This is a small Holarctic genus with a single species in North America distributed across the northern part of the continent. Larvae live in lentic waters. 121. Nemotaulius hostilis (Hagen) (I) Nearctic, transcontinental Distribution: Yukon, Alaska to Newfoundland, West Virginia, Colorado. Yukon records: 4, 10, 12 (ROME, SMDV). Biological information: Adults have been collected in the Yukon 27 June – 27 July. Genus Onocosmoecus. Onocosmoecus is a small Holarctic genus of 2 species (Wiggins and Richardson 1987); larvae live in cool waters of slow streams and lake margins where they are detritivores. 122. Onocosmoecus unicolor (Banks) (II) Holarctic, transcontinental Distribution: Yukon, Alaska to California, Colorado, Michigan, Newfoundland; eastern Siberia and Kamchatka to the Kurile Islands. Yukon records: 6, 8, 10, 11, 12, 14, 16, 17, 19 (ROME, SMDV). Biological information: Adults have been collected in the Yukon 24 July – 20 August. Genus Philarctus. Several species of Philarctus occur in Asia but only one in North America, from Manitoba westward; larvae live in slow streams and small ponds where they are probably detritivores. 123. Philarctus quaeris (Milne) (I) Nearctic, western and north-central Distribution: Yukon, British Columbia to Manitoba, Colorado. Yukon records: 17 (ROME, SMDV).
Caddisflies of the Yukon 809 Biological information: Adults have been collected in the Yukon 26 June – 3 August. Genus Psychoglypha. This is an important Nearctic genus wholly confined to western montane areas except for one northern and transcontinental species, P. subborealis. Larvae are confined to cool running waters and are detritivorous. 124. Psychoglypha alascensis (Banks) (I) Nearctic, western montane Distribution: Yukon, Alaska to California. Yukon records: 10 (SMDV); 14 (ROME). Biological information: Adults have been collected in the Yukon 15 June – 22 August. 125. Psychoglypha subborealis (Banks) (I) Nearctic, transcontinental Distribution: Yukon, Alaska to California, New Hampshire, Newfoundland. Yukon records: 12, 17 (ROME, SMDV). Biological information: Adults have been collected in the Yukon 26 April – 24 July. Genus Sphagnophylax. Sphagnophylax is a relict genus of arctic tundra in the Yukon and adjacent Northwest Territories (Wiggins and Winchester 1984). Larvae of the single species live in transient tundra pools and feed on plant materials. 126. Sphagnophylax meiops Wiggins and Winchester (IV) East Beringian Distribution: Yukon, Northwest Territories. Yukon records: 4 (ROME). Biological information: Adults have been collected in the Yukon 23 July. Family Molannidae The Molannidae are a small family mainly confined to the northern hemisphere; larvae are omnivorous, living in lentic or slowly flowing waters. Genus Molanna. This is an Holarctic and Oriental genus with 6 North American species. Only one, M. flavicornis, is transcontinental; the others are eastern. 127. Molanna flavicornis Banks (II) Holarctic, transcontinental Distribution: Yukon to Nova Scotia, New York, disjunct populations in Colorado; Eurasia. Yukon records: 4, 10 (ROME, SMDV). Biological information: Adults have been collected in the Yukon 2 June – 26 July. Taxonomic notes: Designation of this species as Holarctic hinges on the proposal by Fuller (1987) that it is conspecific with the Eurasian M. albicans Zett. Genus Molannodes. Molannodes is an Holarctic genus with one species widely distributed across northern Europe and Asia, and highly localized in northern North America; a second species occurs in Japan. 128. Molannodes tinctus Zetterstedt (II) Holarctic Distribution: Yukon, Alaska, Northwest Territories, Saskatchewan, Ontario; northern Europe, Asia. Yukon records: 4, 12 (ROME, SMDV). Biological information: Adults have been collected in the Yukon 23 June – 25 July. Family Phryganeidae The Phryganeidae are an Holarctic and Oriental family of 74 species, well represented throughout northern North America (Wiggins in press). Larvae live in lakes and marshes or in slow rivers and streams; they are omnivorous to largely predacious in feeding. The largest caddisflies belong to this family. Genus Agrypnia. This is an Holarctic genus with 10 North American species, mainly transcontinental and northern; all but one of the 10 are known in the Yukon. Larvae occur in marshes, lakes and slow rivers, and are mainly predacious.
