Many of the species of the most diverse families, the sheet web weavers and jumping spiders are quite small and inconspicuous, adults being less than 3 mm (< 1/8 in) long. Most spider species in Ohio are clearly beneficial to humans because of the services they provide as predators on insect pests. Only a few species (widows, recluses) are potentially problematic (Spider Bites) but these species are not commonly encountered here. Little is known about many species of Ohio spiders, some are quite rarely encountered. No species found in Ohio have been legally designated as threatened or endangered. For many, the very word "spider" conjures terrifying or repulsive images. In reality, most spiders are completely harmless to humans and many are very beneficial. To the naturalist, spiders are fascinating in their variety and wonderful for the beauty of their webs.
