Top 20 Most Common Insects in Maple Valley

1. Crowned orbweaver

A common species of orb-weaver, crowned orbweaver (Araneus diadematus) builds large and noticeable webs. Only the females build webs, and they may prey upon their mates before, during or after engaging in sexual intercourse. Crowned orbweaver is reluctant to bite humans and will not do so unless scared or provoked. It avoids danger by vibrating in its web until it becomes a blur, confusing predators.

2. Red rock crabs

3. Yellow shore crab

4. 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.

5. Yellow-spotted millipede

Harpaphe haydeniana reach a length of 4 - 5 cm when mature. The upper surface of the body is black to olive green, and is distinctively marked along the sides with patches of a yellowish colour. Harpaphe haydeniana has approximately twenty body segments, bearing a total of 30 (males) or 31 (females) pairs of legs. The difference between males and females is due to one pair of legs on the seventh segment in males being modified to form gonopods used for sperm transfer.

6. Yellow-faced bumble bee

The yellow-faced bumble bee (Bombus vosnesenskii) is known for its mostly black body with a yellow face. Their population is not dropping, but continued expansion of urban human populations is causing some difficulty for this bee to make nests. But what it does find it tends to monopolize due to its early arrival in the season.

7. Multicolored asian ladybeetle

Often confused for the ladybug, multicolored asian ladybeetle (Harmonia axyridis) is a separate species that, unlike the ladybug, is a household pest. It is considered particularly annoying for its habit of returning to places from which it is removed. One of the most variable species in the world, there are many different colors and patterns multicolored asian ladybeetle may display, making identification potentially difficult.

8. Isabella Tiger Moth

The isabella Tiger Moth (Pyrrharctia isabella) grows into the Isabella Tiger Moth. In folklore, the amount of brown on their band is said to determine the length of the upcoming winter. Over the winter it freezes completely. It prevents the damage of tissue by producing a liquid that preserves the tissue.

9. Black-tailed bumble bee

Bombus melanopygus is a non-woven insect from the family of bees and bumblebees (Apidae). The scientific name of the species was first validly published in 1848 by Nylander.

10. Purple shore crab

11. Pacific forktail

The scientific name of the species was first validly published in 1876 by Selys.

12. Fuzzy-horned bumble bee

13. Brown marmorated stink bug

As evidenced by its name, brown marmorated stink bug (Halyomorpha halys) is most recognizable for its ability to exude a nasty, foul-smelling odor if disturbed. Capable of subsisting on over one hundred species of plant, it has become an enormous pest for many farmers in the U.S., costing over $30 million annually in apple crop losses alone. It often invades homes in autumn, as soon as the weather begins to chill.

14. Northern kelp crab

Sometimes greenish or reddish in color, the northern kelp crab is a vegetarian that enjoys eating kelp. This nocturnal feeder is commonly found around pier pilings and intertidal areas. The northern kelp crab switches its diet seasonally, turning to mussels and barnacles in winter when the kelp is less plentiful. A favorite food of the sea otter, it often meets its fate when this predator is nearby.

15. Eight-spotted skimmer

The eight-spotted skimmer (Libellula forensis) is identified by the eight black markings on its wings. It is occasionally confused with the Twelve-spotted skimmer that is sometimes called the Ten-spotted skimmer. You may attempt to desperately count the number of spots on these fast-moving skimmers, but the major differentiation in this one is the lack of black tips on their wings.

16. Giant house spider

The most common place you'll find giant house spider is in your house. It likes to hide in basements, behind cabinets, or in corners where there's rarely human activity — hence the name house spider.

17. Lorquin's admiral

The lorquin's admiral has brown-black wings, each with a row of white spots across it. Its forewings have orange tips. The wingspan is 4.5 - 7 cm; females are generally larger than males. Larvae are usually yellow with a patch of white on the back.

18. European paper wasp

A particularly hated invasive species in North America, european paper wasp (Polistes dominula) is well-known for its tendency to nest on human porches and sting if approached. Nests are controlled by a dominant female queen, who lays most of the eggs. Dominance among individuals can be predicted by the shape, size and number of spots they display, with more spots signaling greater dominance within the nest.

19. Zebra jumping spider

The zebra jumping spider gets its name from its distinctive black and white stripes. The genus name Salticus comes from the Latin word for "dancing", since it is an agile jumping spider, and the species name Scenicus comes from the Greek word "theatrical" due to its flashy appearance. Their speed and jumping skills make their hunting of other spiders and insects a bit cat-like.

20. Silver-spotted tiger moth

Lophocampa argentata is a bear butterfly from the spider owl family (Erebidae). The scientific name of the species was first validly published in 1864 by Packard.
