|female Eusapyga verticalis on Eriogonum|
The Sapygidae are a small family with only about 80 species described, and they are not of major economic importance. However, some of their host species are important pollinators, and it may sometimes be necessary to control the level of predation on them. (Peterson et al., 1992).
