And they are asking for your help. That might seem like a lot, but more say, 20, would let the scientists make some conclusions about the rarer species hiding out in our homes. Find out below how to participate.
Scientists Say: Venomous. Explainer: Eek! What if you get bed bugs? Analyze This: A massive annual insect migration. Spiders eat insects — and sometimes veggies.
Once in your garden, they'll grab small caterpillars, leaf hoppers, aphids, and beetle larvae with their front legs and use their beaks to suck them dry. As adults, these beautiful insects typically prefer pollen and nectar. But as larvae they're voracious, chowing down on as many as 60 aphids in an hour which is probably how they earned the nickname " aphid lion ". They also take care of mealy bugs, spider mites, and insect eggs. Many stink bugs cause damage to plants, but these arthropods are your friends: They prey on more than species , including pests like the larvae of cabbage worms, the Mexican bean beetle, and the Colorado potato beetle.
In at least one case, a single spined soldier bug devoured army worm larvae over the course of a season. They can be identified by the "spikes" on each shoulder.
Don't worry: Though these yellow- and black-banded flies have looks and a diet in common with bees as adults, they, too, are pollinators that eat pollen and flower nectar , they can't sting you.
If the wasp egg fails to hatch, the spider can recover. More photos of Tarantula Hawk in Calphoto. The Pacific Green Sphinx has a short and stout body. Forewing upperside is green to olive green with pink and brown markings. Hindwing upperside is pale rose pink with a darker submarginal band. The caterpillars feed on evening primrose and clarkias.
Adults feed on flower nectar. They can be found in oak woodlands, and grasslands. Photo Credit - Rob Irwin. More photos of Pacific Green Sphinx in Bugguide. The White Lined Sphinx is also know as the hummingbird moth because of the similarity in appearance and flight characteristics.
The forewing is dark brown with a tan stripe which extends from the base to the apex. There are also white lines that cover the veins. The black hind wing has a broad pink median band. It has a wingspan of 2 to 3 inches.
The white-lined sphinx may be encountered from March to October. This moth's rapid wing movement resembles a hummingbird in flight when it hovers over flowers while it feeds.
They may also be seen darting in a back-and-forth pattern over nectar sources, or larval food sources. Adult food consists of nectar from a variety of flowers including columbines, larkspurs, honeysuckle, clovers, and thistles.. Photo Credit - Clay Nichols.

Body size is up to three inches long and two to three inches tall with a leg span of three to five inches. Male tarantulas are longer and slimmer than females and have much smaller abdomens than females. The exoskeleton outer shell includes a fused head and thorax connected at a narrow waist to an oval-shaped abdomen. They have eight marginally functional eyes in two groups on their forehead.
Their mouth and two backward-pointing fangs are below the eyes. They also have two pedipalps leg-like appendages for food handling near their mouth. All of California's native tarantulas are in the genus Aphonopelma. They are invertebrates, a general term for all multiple - celled animals that lack an internal skeleton. Tarantulas mainly eat insects and other arthropods, and they can fast for up to a month.

Yellow Jackets are considered quite beneficial to agriculture since they feed abundantly on harmful flies and caterpillars, but they become a nuisance when they scavenge for food at picnics or other outdoor venues where food or sugary beverages are served. They are important scavengers of dead animals, and fierce predators of other insects. They feed these insects and scavenged meats to their larvae.
Adults eat nectar. Yellow Jackets are social wasps living in colonies containing workers, queens and males. Photo Credit - Sean McCann. More photos of Yellow Jacket in Calphoto. These flies, that resemble bees or wasps, are expert fliers and can hover or fly backward, an ability possessed by few insects other than syrphid flies. Adults often visit flowers for nectar or may be seen around aphid colonies where they feed on honeydew secreted by the aphids and lay their eggs in the colony.
The adults are considered to be important agents in the cross pollination of some plants. The larvae are important predators, feeding primarily on aphids that attack plants. It has transverse yellow bands on the abdomen, and two oblique yellow marks near the tip. Photo Credit - Bob Barber. More photos of Flower Fly in Bugguide. The devastating grasshopper is a major pest in California destroying rangeland forage, orchards, grains, vegetable crops, and gardens.
Populations, ever present on rangeland in the coastal and Sierra Nevada foothills of California, fluctuate annually in size. Significant damage to rangeland occurs when densities rise to outbreak levels. Adults make clicking noises in flight and expose brightly-colored body parts to attract mates.
Hungry locusts will feed on all kinds of plants. Photo Credit - Eugene Zelenko. More photos of Devastator Grasshopper in Bugguide. These grasshopper relatives live in trees and shrubs and are distinguished by their bright green color. Adults have wings and 'sing' in the trees.
The wingless nymphs, especially in the younger stages, are multi-colored. The diet of the Katydid includes leaves, flowers, bark, and seeds. Many katydids have wings resembling leaves, making them difficult for predators to detect among foliage. Photo Credit - Alana Post. More photos of Katydid in Bugguide. Adult beetles are soft and somewhat flattened, with parallel sides, long legs and long, usually threadlike antennae. The common name of the group, soldier beetle, has arisen as a result of most members of the family being red and black in color.
Adults can be found mostly on vegetation, often on flowers and the larvae can be found in leaf litter, loose soil, rotten wood, etc.
Adults eat nectar, pollen, aphids and other insects and the larvae are fluid-feeding predators, feeding on insect eggs and larvae. More photos of Soldier Beetle in Bugguide.
This is a medium-sized dragonfly with a length of 1. The abdomen appears broad. Mature males have partially clear wings, with the central third portion of each wing marked with a large dark patch and a small dark spot at each wing base.
The top and sides of the abdomen are pruinose dusty or frosty white, with the white extending onto each hind wing along the bottom edge of the dark spot. The thorax between the head and abdomen may have several lines or spots of yellow. In females and immature males, each wing has a small dark patch at the base, at the center, and at each tip the patch at the tip may be more yellowish.
The thorax and abdomen are brown marked with yellow. They are found in ponds, lakes, marshes, streams; adults may also be found some distance from water. The adults will eat almost any soft-bodied flying insect including mosquitoes, flies, butterflies, moths, mayflies, and flying ants or termites.
It is also known as the Long-tailed Skimmer. More photos of Common Whitetail Dragonfly in Calphoto. More photos of Widow Skimmer Dragonfly in Calphoto. Western Pondhawk females and immature males are a uniform bright green from the face to the tip of the abdomen, while mature males are covered with a powdery slate blue a condition called pruinose.
The sides of the thorax may have several small patches of hazy green. Immature males start out like females. The males take a few weeks to change color; first the abdomen becomes blue, then the front of the thorax, and lastly, the sides of the thorax. Male Western Pondhawks have dark blue eyes. It can be found near warm, marshy lakes and ponds.
The adult dragonfly will eat almost any soft-bodied flying insect including mosquitoes, flies, butterflies, moths, mayflies, and flying ants or termites. This species has large, powerful mandibles for its size, and often eats comparatively large insects, such as butterflies and other dragonflies.

The brown abdomen becomes increasingly whitish or steely blue as the dragonfly gets older.
The eyes are dark brown to black. Immature males and females have the prominent brown banding on the wings, but lack the white.
