Insects, Spiders, Centipedes, Millipedes
More species of insects exist than all other animal species combined.
Despite being the most diverse and abundant animals in natural ecosystems, insects and other related invertebrates (e.g. spiders, millipedes, etc.) are greatly under appreciated. They have survived on earth for more than 300 million years and may possess the ability to survive for millions more. Insects are vital to the complex cycle of life, furnishing food for other creatures and breaking down natural materials to chemicals and nutrients for recycling into new life. Whirling, buzzing, singing, chewing, vibrating with energy, they are all around us.
Insects and their relatives, along with other species of plants and animals in the park, can be enjoyed through such activities as observation, study, and photography. They are protected from collection, harassment, or other activities that may injure or alter their environment.
Studies of invertebrates in CVNP include butterfly monitoring and inventories of dragonflies, bees, ants, and spiders. Butterflies are important pollinators and are also significant in nutrient recycling, both as consumers and as prey for other species. Many species are restricted to unique ecological conditions, making them valuable indicators of ecosystem quality and change. In 1996 CVNP was invited to participate in a long term butterfly monitoring program initiated by the Cleveland Museum of Natural History. After eight years of monitoring, a total of 54 species of butterflies have been recorded along the selected transect in CVNP. The long term project has grown to over 65 transects in 22 counties in all parts of Ohio.
The 20 most commonly seen butterflies in CVNP are the pearl crescent, European cabbage white, little wood satyr, orange sulphur, eastern tailed blue, common wood nymph, European skipper, monarch, silver-spotted skipper, viceroy, great spangled frittilary, tiger swallowtail, clouded sulphur, American copper, wild indigo duskywing, Zabulon skipper, red-spotted purple, least skipper, black swallowtail, and Acadian hairstreak.
Dragonflies (Order Odonata) are among the best insect fliers, capable of hovering and even flying backwards. They have four silky transparent wings and huge wrap-around eyes. With names like jewelwing, dancer, rubyspot, damsel, and bluets, dragonflies are considered beneficial insects that feed on mosquitoes, gnats, and flies and are harmless to humans. The biggest threat to dragonflies is the loss of wetland habitats and pollution of streams.
Did You Know?
American Indians in the Cuyahoga Valley were influenced by the Hopewell Culture, which created large mound complexes in central Ohio from 100 B.C. – A.D. 500? In the Cuyahoga Valley, American Indians built small mounds rather than large ceremonial centers.
