Pteronarcys dorsata

Freshwater Invertebrate Collection

SeasonalityAdults emerge in early May. IdentificationThis is the largest of Alberta stoneflies. The species is distinguished by its large size (male length = 40 mm; females = 60 mm), and the presence of gills (nymphs) or gill remnants (adults) on all thoracic segments and the first two abdominal segments. Male genitalia have the ninth sternum straight near the tip; the epiproct is large and flattened with its tip expanded. Female subgenital plate is straight, or with two small projections extending just to the edge of the ninth sternite. Nymphal females have the projection on the tenth tergum projected postero-dorsad to a point; nymphal males have the projection extended postero-ventrad with a peg on the caudal surface. Mature male nymphs have a nearly rectangular projection posterad on the ninth abdominal sternum.

Ptilostomis ocellifera

Freshwater Invertebrate Collection

SeasonalityAdults fly from May though to September. IdentificationAdult hindwings usually has a dark brown, angulated marking near the apex and the apical border is darker brown. In males, the cercus is long, slender, and deeply bifurcates to a pair of long, slender processes. The dorsal process is distally rounded and the ventral process is acuminate (Wiggins, 1998).

Rhyacophila angelita

Freshwater Invertebrate Collection

SeasonalityAdults can be found approximately late May to late June. IdentificationAdult antennae are yellow with the vertex of the head brownish yellow. Spurs are yellow-brown. In males, the dorsum of segment 9 is about 5 times the length of the sternum. Distal article of the clasper has an upper, basal rounded process directed dorsad (Nimmo, 1971).

Rhyacophila rickeri

Freshwater Invertebrate Collection

SeasonalityAdults have been collected in October. IdentificationAdult antennae are brown and the vertex of the head is anteriorly dark brown and lighter posteriorly. Spurs are yellow-brown. The dorso-posterior edge of segment 9 in males is produced posterad into a thumb-like process. Segment 10 is evident as a pair of rounded lobes (Nimmo, 1971).
