Did you know that there are more than 20 times more species of moths than butterflies in Ohio? There are more than 160,000 species of moth worldwide and more than 3,000 of those can be found right here in Ohio. And new species are being discovered and catalogued every year!
Only about 1% of moth eggs make it to become adult winged wonder. Almost 99% of caterpillars die due to predators such as birds, parasitoid wasps and flies and other predatory animals. The world’s largest moth is the giant atlas moth from southeast Asia with a wingspan of more than 10 inches. The smallest is the Nepticulidae family with only a 3 millimeter wingspan.
So what’s the difference between a moth and a butterfly? Both butterflies and moths go through a complete metamorphosis. Both also have a long tongue called a proboscis and tiny scales that cover their bodies and wings. But that’s where a lot of their similarities end.
|Fly at night||Fly during the day|
|Feathery antennae||Single filament with a clubbed tip|
|Rest with wings open||Rest with wings closed|
|Fatter and hairier||Typically more colorful|
|Pupal stage: soft cocoon filled with silk, old leaves and other plant parts||Pupal stage: Hard, smooth chrysalis|
Why should you care about moths you may ask? Well, they are beautiful; help feed other animals such as bats, spiders and birds; and lastly, they are very important pollinators. Moth caterpillars provide a food source for about 75% of breeding Ohio songbirds, so without the moths we’d lose a lot of the songbirds.
Moths are very important pollinators. Moth-pollinated plants are usually white and emit a fragrance at night to attract the moths. Evening primrose and certain orchids such as the prairie fringed orchid are only pollinated by moths. Sphinx moths are specifically attracted to this orchid species.
