The Everglades is a subtropical wetland located in the southern portion of the U.S. state of Florida, comprising the southern half of a large watershed. The system begins near Orlando with the Kissimmee River, which discharges into the vast but shallow Lake Okeechobee. Water leaving the lake in the wet season forms a slow-moving river 60 miles (97 km) wide and over 100 miles (160 km) long, flowing southward across a limestone shelf to Florida Bay at the southern end of the state. The ever-changing Everglades are shaped by water and fire, with frequent flooding in the wet season and drought in the dry season.

The longhorn beetles (Cerambycidae; also known as long-horned beetles or, more archaically, llongicorns) are a cosmopolitan family of beetles, typically characterized by extremely long antennae, which are often as long as or longer than the beetle's body. The family is large, with over 20,000 species described, slightly more than half from the Eastern Hemisphere. Several are serious pests, with the larvae boring into wood, where they can cause extensive damage to either living trees or untreated lumber.

Elizabeth I (7 September 1533 &ndash; 24 March 1603) was Queen of England and Queen of Ireland from 17 November 1558 until her death. Sometimes called The Virgin Queen, Gloriana, or Good Queen Bess, Elizabeth was the fifth and last monarch of the Tudor dynasty. The daughter of Henry VIII, she was born a princess, but her mother, Anne Boleyn, was executed three years after her birth, and Elizabeth was declared illegitimate. Her brother, Edward VI, cut her out of the succession. His will, however, was set aside, and in 1558 Elizabeth succeeded her half-sister, the Catholic Mary, during whose reign she had been imprisoned for nearly a year on suspicion of supporting Protestant rebels.
