California is home to a variety of native insects and spiders found in rural, suburban, and urban areas. It is estimated that over 30,000 species are found in California and new species are still being discovered.
Insects and spiders provide many ecosystem services such as pollination of plants and crops, predation of other animals, seed and nutrient dispersal. They are also a key food source for many species, including other insects and spiders, birds, and mammals such as black bears and coyotes. They may cause potential conflict due to agricultural or property damage and concerns for human health and safety.
