At the Beach 8/21/11
We're expecting thunderstorms in the late afternoon and evening; we hope it doesn't interfere with the ZZ-Top/Joan Jett concert this evening at the Calvert Marine Museum.
Black Swallowtail butterfly on some vines.
Ecphora, Maryland' state fossil. We find a lot of fragments, a few that are mostly complete, and have yet to find one with the complete spiral. This one was pretty intact except for the tip.
Staghorn Sumac. The fruits are seedy but edible, and contain large quantities of ascorbic acid (vitamin C) which makes them quite tart. It is sometimes used to make a form of lemonade (sumacade?). Don't use Poison Sumac by mistake (it has white berries). The fruit is also a favorite of some birds.
