Sept. 8, 2021

The Rocky Mountain snail is a species of land snail common throughout North America's Rocky Mountains but is one of 40 varieties endemic to 欧美口爆视频.

Western Conifer-Seed Bug

Sept. 1, 2021

The Western Conifer-Seed Bug is a true bug native to the pine forests of western North America that has quickly spread eastward since the 1950s. Pest specialists surmise that these bugs were accidentally introduced to eastern North America through wooden shipping crates on trains or through commercial Christmas trees. After becoming established in eastern North America, they were repeatedly introduced across Europe, Asia, and northern Africa. By the late 1990s, the Western Conifer-Seed Bug was recorded in Northern Italy and has since been found on almost all continents with the exception of Antarctica.

Toad Bug

Aug. 11, 2021

Toad Bugs (Family: Gelastrocoridae) really live up to their name as they spend much of their time in or around water. Their hopping about can cause them to easily be mistaken for their Amphibian counterparts. These true bugs can be found in temperate zones near water, but their diversity increases near the tropics. Immature nymphs in this family will cover their exoskeleton with sand, which is thought to increase protection and provide a layer of camouflage to potential predators. As adults, these big-eyed bugs exhibit intricate color patterns and textures on their exoskeleton, which increases their ability to blend into their shore-line habitats as they sit and wait for unsuspecting prey.

Monarch butterflies (Danaus plexippus) are perhaps one of the most well-known insects in North America.

Males can be distinguished from females by the two black spots in the center of their hind wing, which females do not have. Can you tell if this Wonder of the Week is a male or female? The caterpillars of this species, found on milkweed, are striped yellow, black and white. The chrysalis is light green with yellow spots along the edge.
