Common NameSpotted spreadwing SeasonalityLate summer, mid July to early October (Walker). IdentificationThorax blackish-bronze above, yellowish below, with clear wings. Two dark spots are found on the metepimeron. Male: 34-36 mm long, up to 42 mm in some populations. Inferior appendages less than half the length of superior appendages. Pruinosity develops with age at wing base and abdomen (segments 1,2, 8, 9 and 10). Female: 32-34 mm long, up to 39 mm in some populations.

Life History
Oviposition occurs in tandem well above the water line as late as mid September (Walker). The eggs complete katatrepsis (revolution of the embryo), and then enter a state of diapause, in which they remain until the…
Oviposition occurs in tandem well above the water line as late as mid September (Walker). The eggs complete katatrepsis (revolution of the embryo), and then enter a state of diapause, in which they remain until the following spring. When the eggs are wetted, development resumes. Adults tend to emerge en masse (Corbet).
Conservation Common throughout the south, decreasing further north (Walker). Diet Info Gleans small invertebrates from the foliage. The nymphs prey on aquatic invertebrates. Range
Throughout Alberta, more prevalent in the south. Walker lists it as general in southern Alberta, but specimens have been collected up to N.W.T. Found throughout Canada, much more commonly in the south. Widespread…
