This mite was accidentally introduced into Germany from Chili in 1958 and subsequently shipped to other parts of the world, including California and Florida, from Germany.This predatory mite consumes 2 or 3 adult females or several dozen egg in a day. Adult females are approximately 0.5 mm long, reddish in color, pear shaped and active at room temperature, Immatures & males are smaller and lighter in color. Eggs are oblong. About 80% are females. At optimum temperatures Phytoseiidae can develop from egg to adult in 7 days and live for up to 1 month. A well-fed female will lay about 50 eggs in her lifetime. Prey consumption is up to 7 adult spider mites or 20 eggs per day.〔(【引用サイトリンク】 url=http://www.hydro-gardens.com/spidermite.htm )〕 ==Environment== Ideal temperature range is 70–85 °F (20–30 °C) with relative humidity of 70–80% inside the plant canopy.
