Dicosmoecus atripes

Freshwater Invertebrate Collection

SeasonalityThere are no recent records from Alberta. IdentificationAdult antennae are dark brown and the vertex of the head is dark brown with yellowish warts. In males, there is a ridge on the meso-basal ledge of the clasper. The distal article of the clasper has a distal tooth directed posterad (Nimmo, 1971).

Glyphopsyche irrorata

Freshwater Invertebrate Collection

SeasonalityAdults are flying from early September to early October and March to May. IdentificationAdult antennae are light reddish brown with dark brown scapes. Vertex of the head is dark brown with a yellow posterior edge. Spurs are brown. Forewings are greyish chocolate-brown, irrorate with larger hyaline patches throughout. In males, the sternal area of segment 9 is constricted. Segment 10 process is short, slender and curved dorsad (Nimmo, 1971).

Helicopsyche borealis

Freshwater Invertebrate Collection

SeasonalityAll season; adults have a wide-spread emergence period and flight period (LaFontaine, 1981). IdentificationAdult head and body varies from pale to straw yellow. The wings are light brown with dark brown mottling and straw coloured legs (LaFontaine, 1981). Male clasper is huge, directed postero-dorsally and distally widened to an approximately rounded object with a dentate perimeter.

Hydropsyche betteni

Freshwater Invertebrate Collection

SeasonalityAdults fly from late May to early October. IdentificationMale forewings are red-brown, and brown tinted hindwings. The antennae are red-brown, yellow-brown vertex, and a deep red-brown thorax. Male legs are brownish-yellow and red-brown in females. The distal article on the clasper is grooved on the disto-posterior face (Nimmo, 1987).

Hydropsyche bifida

Freshwater Invertebrate Collection

SeasonalityAdults can be found in late May to mid-October. IdentificationThe forewings of males are pale golden-brown and fairly irrorate. Antennae are brownish-yellow and the vertex is a yellow-brown. The legs are yellow to pale straw with straw-coloured spurs. The male genitalia is similar to H. vexa, but the lateral membranous lobes of the aedaagus in H. bifida are larger and have a large, stout terminal spine. As well, the tips of the lateral lobes are directed anterad (Nimmo, 1987).

Hydropsyche depravata

Freshwater Invertebrate Collection

SeasonalityAdults can be found flying in July. IdentificationMale forewings are grey-brown and uniformily irrorate, hindwings faintly tinted grey-brown. Antennae are red-brown, vertex dark brown and thorax is dark brown to red-brown laterally. The legs are straw coloured and males have brown spurs and females have yellow spurs. The tip of the male aedeagus is cut square, slightly curved and the ventral lobe is rounded (Nimmo, 1987).
