Most Common Insects
1. Mourning cloak
The state insect of Montana, mourning cloak (Nymphalis antiopa) owes its name to a visual comparison with a girl who, disliking mourning, allows a few inches of color to show from under her mourning garb. Among the longest-lived butterflies, individuals may persist for as long as eleven to twelve months. It is a powerful flier, with vagrants often found many miles from the usual migration paths.
2. Silvery blue
Its upperside is a light blue in males and a dull grayish blue in females. The underside is gray with a single row of round spots of differing sizes depending upon the region. Wingspan is from 1.8 - 3 cm. 
3. Pearl crescent
The pearl crescent (Phyciodes tharos) is an orange butterfly that lives in open areas that are generally moist and sunny. These butterflies are attracted to puddles, and the males will often fight with other male butterflies that land near the same puddle. However, females are not as aggressive and prefer to stay in groups.
4. Atlantis fritillary
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.
5. Seven-spotted ladybug
Seven-spotted ladybug (Coccinella septempunctata), known in North America as the "seven-spotted ladybug," is the most common species of ladybird in Europe and the official state insect of five U.S. states. While not native to North America, it has established itself there after being introduced to control aphid populations. Its bright coloring deters predators, and it may also play dead or secrete foul-smelling liquids to discourage consumption.
6. Clouded Sulphur
The scientific name is Colias philodice, also known as the clouded Sulphur. It is very commonly seen in North America with pale yellow wings, which have solid black borders on the upper surface and a doubled hindwing spot trimmed in brownish red. Interestingly, the wing color of the clouded Sulphur varies in a seasonal manner from white to yellow and the spots on the wings also change as well, being more pronounced during the cool months in spring and fall.
7. Western honey bee
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.
8. Cabbage white
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.
9. Common alpine
Erebia epipsodea, the common alpine, is a butterfly species of the subfamily Satyrinae of family Nymphalidae. It is found in North America from Alaska south through the Rocky Mountains to northern New Mexico and east across the prairie provinces to southwest Manitoba. The wingspan is 34–45 mm. Adults are on wing from mid-June to early August. The larvae feed on various grass species.
10. Red-Spotted Purple
The red-Spotted Purple (Limenitis arthemis) is a beautiful butterfly that shows off a metallic-blue color. They are also known as White Admirals due to the brilliant, white band that is seen on them. Males are incredibly aggressive in defending areas that have high female traffic. They will regularly patrol these areas to ensure other males do not take over claimed territories.
