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.

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.
