Top 20 Most Common Insects in Saskatoon

The moths are very different in size and reach a wing span of 27 to 40 mm. They have very variable wing tops, from pale yellowish and ocher yellow to brownish. Mostly on the forewing underside near the tip of a small, brightly knurled eye spot is formed, which often shines on the top. At the leading edge there are sometimes further smaller eye spots. On the darker colored light, dark brown or gray rear wing underside as well usually several white or brightly gerandete black Augenflecken are to be seen with silver point, which can also be missing. Unmistakable feature of the species is there a white irregular and interrupted bandage, which already begins at the front edge of the hind wings. The egg is large, ovate and very finely meshed. It is initially pale yellowish green and later marbled reddish brown. The hairless caterpillar is about 25 millimeters long and has small, yellowish point warts and is tapered backwards. It is light green in Europe with a narrow, dark midline and a narrow upper white-yellow and dark upper bound and a lower broader, pale yellow and sharply delineated line. In North America, it varies from green to olive green to brown and has alternately bright and dark vertical stripes. At the end of the abdomen they carry two small pink lobes, which mark the caterpillars of the eye-butterflies (Satyrinae). The head is green or tan. The pupa is green in Europe and North America with light longitudinal lines and in California green to brown.

Western honey bee（Apis mellifera） is the most common species of honeybee in the world. Among the first domesticated insects, its cultural and economic impact on humanity has been vast and far-reaching, providing honey, wax and its services as a pollinator. Western honey bee faces challenges worldwide, such as colony collapse disorder, and populations are thought to be decreasing.

Its upperside is dark orange with many rows of black markings and black wing margins. Its underside is a light brown with many silvery-white spots. Wingspan ranges from 5 - 6 cm.

The painted lady is a migratory butterfly that spends part of the year in Northern Africa and then migrates to Europe during the warmer months. Although the adults feed on nectar from flowers, the larvae feed on the leaves of nettles and thistles.

The Melissa blue (Plebejus melissa) is a butterfly of the family Lycaenidae. It is found in western North America, from Canada to Mexico. The Karner blue (Plebejus melissa samuelis) is a subspecies of the Melissa blue, and was described by the novelist/lepidopterist Vladimir Nabokov. The wingspan is 22–35 mm. Below, the hindwing orange submarginal band, often with distal iridescent blue points, help to distinguish this species from the more muted colors and markings of the similar Plebejus idas. The marginal line is wider where the veins intersect. The fringes are not checked. The butterfly flies from April to August depending on the location. The larvae feed on Lupinus, Medicago and Lotus species.

Cabbage white (Pieris rapae) derives its common name from its habits as a caterpillar, which is a ferocious pest for cabbage, kale and broccoli farmers. In North America, it is one of the first butterflies to emerge in spring, heralding the beginning of the season.

The wingspan is 3.5 - 4 cm .

The saber-spine-bug (Tetrix subulata) belongs to the family of spiny-throats (Tetrigidae) in the order of the short-term terrors (Caelifera).

Rather than for its coloring, goldenrod crab spider (Misumena vatia) is named for its tendency to hunt within sprays of goldenrod. This species is capable of catching and consuming prey several times larger than itself, such as dragonflies or grasshoppers. Loyal parents, the females will guard their eggs until they hatch and the tiny spiders disperse, after which the female will die.

Lestes unguiculatus, the lyre-tipped spreadwing, is a species of spreadwing in the damselfly family Lestidae. It is found in North America. The IUCN conservation status of Lestes unguiculatus is "LC", least concern, with no immediate threat to the species' survival. The population is stable. The IUCN status was reviewed in 2017.
