| | Good Bug, Bad Bug: Spider Mites |
 | | Spider mites are not insects, but arachnids, along with spiders. | | | Spider mites have been found on over 300 host plants; violets, chickweed, henbit, blackberry, hollyhocks, and several types of weeds are common host plants from which spider mites move to other plants. | | | Spider mites feed by piercing the epidermal cells with their sharp, mouthparts, and sucking out sap. |

| | Spider mites can be detected by carefully inspecting thatch and grass blades with a 10X hand lens or magnifier for foraging clover and winter grain mites, or for colonies of twospotted and Banks grass mites colonies on the undersides of leaves. | | | Early season spider mite infestations are typically found on grass blades, but spread to other parts of the plant as mites increase in abundance. | | | Winter grain mites are most abundant during the winter and early spring months and can be observed on sunny days in the thatch and crowns of the grass plants. |

| | Spider Mites Management Guidelines--UC IPM |
| | The spider mites, also called webspinning mites, are the most common mite pests and among the most ubiquitous of all pests in the garden and farm. | | | Spider mites live in colonies, mostly on the under-surfaces of leaves; a single colony may contain hundreds of individuals. | | | Spider mites are generally favored by hot, dusty conditions and are usually found first on trees or plants adjacent to dusty roadways or at margins of gardens. |

| | Pred.Mite Intro |
| | Spot spraying of localized outbreaks of thrips and spider mites with short-residual chemicals that are compatible with the predatory mites or, on a small scale, with insecticidal soap or horticultural oil may help to keep infestations under control while the predatory mite population establishes. | | | There are, however, many species of beneficial predatory mites, several of which are mass reared commercially for the management of spider mites, thrips, and other pests in greenhouses and some field-grown crops.They are predatory in both the nymph and adult stages. | | | These beneficial mites are used against spider mites and several species of thrips by greenhouse flower, ornamental, and vegetable producers in Canada and Europe, and by some United States growers. |

| | Spider Mites on Landscape Plants |
| | Spider mite eggs that have not yet hatched are unaffected by most miticides; the same may be true of larvae and nymphs that are molting. | | | Spider mites have needle-like mouthparts and feed by piercing the leaves of host plants and sucking out the fluids from individual plant cells. | | | Spider mites are common pests in the urban landscape and can inflict serious damage to trees, shrubs and flowers. |

| | Spider Mites |
| | Spider mites (Family: Tetranychidae) are classed as a type of arachnid, relatives of insects that also includes spiders, ticks, daddy-longlegs and scorpions. | | | Spider mites develop from eggs, which usually are laid near the veins of leaves during the growing season. | | | Most spider mite eggs are round and extremely large in proportion to the size of the mother. |

| | UC IPM: UC Management Guidelines for Spider Mites on Alfalfa |
| | Spider mites are usually found on the undersides of leaves, with colonies beginning on the lower (older) leaves and moving upward on the plant. | | | Spider mites are small pests, with adults about the size of a small pinhead, variable in color (green or yellow) with dark pigmented spots. | | | Western flower thrips are often an effective predator of spider mites, migrating into alfalfa from surrounding crops as their host plants desiccate and/or attracted by alfalfa foliage following an irrigation. |

| | European Red Mite & Twospotted Spider Mite |
| | Adult twospotted spider mites are only about.35 mm (1/60 inch) in length, and have a black spot on each side of their bodies, which range in color from white to light red. | | | Since mite development is linked to host plant stress, cultural practices and varieties which limit plant stress in times of drought will also minimize the development of spider mites. | | | This mite is considered a secondary pest, as it typically only builds to damaging levels after its natural enemies have been depleted by insecticide applications used to control codling moth or other pests. |

| | Mites and some insects have piercing-sucking mouthparts, so the damage to plants is often similar. | | | Mites, spiders and ticks are not insects, but belong to a closely related group called the arachnids. | | | Unlike two-spotted mites, spruce spider mites are most active and damaging during the spring and fall when the temperatures are cooler and rainfalls are more frequent. |

| | The two-spotted spider mite overwinters as an adult in the soil; the honeylocust mite overwinters as an adult in bark crevices on the trunk and branches. | | | Spider mite damage to foliage is similar on all host plants: fine stippling which progresses to an overall bronzing of the leaves. | | | Certain lady beetles, thrips, and predaceous mites provide some degree of natural control for spider mite populations, but usually only after mite infestations have become destructive. |
