Thanks for visiting Maryland butterflies.
This small East Coast state hosts approximately one hundred and sixty butterfly species. A changing climate and other factors means that their population levels change over the years, some long term, some short term.
The top picture shows a Horce’s Duskywing. It’s found in Open oak woods and marshes throughout the state.

Butterflies: Whites and Yellows
Cabbage White butterflies originated in Europe and unintentionally arrived in the United States in the mid-19th Century. Since then, they expanded their range from coast to coast. They will be very common in Maryland gardens. Males have one black spot on the top wing. Females have two black spots.
Here’s a list of the rest of the white butterflies and yellow butterflies documented in the state.
West Virginia White
Great Southern White
Large Orange Sulphur
Blues, Hairtreaks and Coppers
The Great Purple Hairstreak is really one great butterfly. It’s larger than the average sized hairstreak and characterized by one short and one long tail on hindwing. As the picture shows, the side of the butterfly shades purple with metallic gold markings near the tail. Abdomen is blue on top and red-orange underneath. They are regionally distributed. Look for areas in the coastal plain with mistletoe, the larval host plant.

Brush Footed Butterflies
Maryland gardens are filled with orange winged butterflies, and most belong to the Brush Footed family. It is important to note that in the family, the types of butterflies one might see as a tourist or resident is dependent on the ecosystem. Maryland documents the existence of its butterfly species according to five such ecosystems: Appalachian Plateau (AP), Ridge & Valley (RV), Piedmont (PD), Upper Coastal Plain (UC), Lower Coastal Plain (LC), or Coastal Plain (CP).
Very few of the Brush Footed species are documented state wide. The Gulf Fritillary, for example, gets characterized as a stray insect in the Coastal Plain and the Piedmont regions. Speaking of fritillaries, most of Maryland’s species are fairly easy to identify once spotted. Photographers should get pictures of the top of the wings and a side view with the wings folded to help with the identification process.
The picture shows a Baltimore Checkerspot the official state butterfly of Maryland. It’s range does extend outside the state.

Maryland Butterflies: Swallowtails
Apart from the Applachain and Palamedes Swallowtails, all of Maryland’s swallowtail butterflies can be found state wide.
The larvae of this Pipevine Swallowtails use Dutchman’s pipe as the host plant, hence the name. Somewhere in the Pipevine Swallowtail story the discussion of chemicals in the plant that make adults a toxic food source for birds also gets discussed.
It’s one of five Maryland swallowtails that have dark wings on the top.
- Pipevine Swallowtail
- Zebra Swallowtail
- Black Swallowtail
- Appalachian Tiger Swallowtail
- Eastern Tiger Swallowtail
- Spicebush Swallowtail
- Palamedes Swallowtail
- Giant Swallowtail
Two metalmark species, the Little Metalmark and the Northern Metalmark also find a home in the state.
Butterfly identification usually begins with color. So, the Maryland butterflies section divides into nine different categories based on wing color and/or the butterfly family to help all visitors and members easily categorize and document their butterfly pictures.
