Name this moth or butterfly

Asked July 27, 2019, 9:35 AM EDT

While hiking at the Howard County Nature Conservancy, I spotted these two insects in the grass. Are they moths or butterflies? Could you tell me the common name as well as the scientific name? How can I tell whether an insect is a moth or a butterfly? Thank you! Virginia

This looks like an Eastern Tailed-Blue (Cupido comyntas). It is one of Maryland's most common butterflies. https://www.marylandbiodiversity.com/viewSpecies.php?species=531

Butterflies usually close their wings when they are resting whereas moths lay their wings open. Butterflies have long, thin antennae. In many moths, they are shorter and look feathery.
