Red Spotted Purple (Limenitis arthemis astyanax): This is a mimic of the poisonous Pipevine Swallowtail. Readily hybridizes with the sub-species White Admiral below to form several ntermediate "proserpina" types. Location: Pine Lick Trail and Fifteen Mile Creek Rd, Green Ridge State Forest, MD.

Brushfoots (con't)

 

Northern Crescent (Phyciodes cocyta): 1 7/8 inches max. A more northern species that, oddly, has a large distribution in WV and a narrow band through PA, roughly following the Allegheny Mountains. Very similar to P. tharos  - the Pearl (below) Crescent which is much more common in our region. Top photo by Anita Mueller.

Whites and Sulphurs

Cabbage White (Pieris rapae): 1.75 inches. One of the most common butterflies in our region. Caterpillars can cause economic damage to cabbage, broccoli and collards crops. Males have one black spot. Females have two. on each forewing. Tip of forewing is black on top and yellow underneath.

Satyrs/Milweed Butterflies

Monarch Butterfly (Danaus plexippus): Some Monarchs are toxic to predatory birds because of the juices from certain milkweed that they consume. Their orange color signals a warning to birds to leave them alone. Other orange butterflies are often called "mimics" because it is thought this color causes birds to also leave them alone even though they are not toxic.

Eastern Oak Looper (Phigalia titea): Causes defoliation in the spring. Host species attacked include the red and white oak groups, maples, elms, hickories, ash, and cherry. Heavy defoliation usually occurs in May and June and can cause growth loss and mast reduction. Photo by Ken Clark.

Caterpillar of the Hickory Tussock Moth (Lophocampa caryae) - Feeds on a variety of trees. Location: PA. Photo by Pat Roberts.
