Question: What state does Whitetop, Virginia and Virginia Creeper Trail have in common?
Context: The Vitaceae are a family of dicotyledonous flowering plants, with 14 genera and ca 910 known species, including the grapevine and Virginia creeper.  The family name is derived from the genus "Vitis".  The name sometimes appears as Vitidaceae, but Vitaceae is a conserved name and therefore has priority over both Vitidaceae and another name sometimes found in the older literature, Ampelidaceae.  In the APG III system (2009) onwards, the family is placed in its own order, Vitales.  Molecular phylogenetic studies place the Vitales as the most basal clade in the rosids. The Virginia Creeper Trail is a 35 mi multi-purpose rail trail in southwestern Virginia.  The trail runs from Abingdon to Whitetop, Virginia, near the North Carolina state line – through National Forest and crossing numerous restored trestles and crossing the Appalachian Trail. Pettigrew Wildlife Management Area is a 934 acre Wildlife Management Area (WMA) in Caroline County, Virginia.  Most of the long and narrow area's land was once part of Fort A. P. Hill.  It is largely dominated by forests, including hardwood stands dominated by oak and beech, as well as stands consisting mostly of Virginia and loblolly pine.  Lower vegetation including greenbriar, honeysuckle, and Virginia creeper may be seen reclaiming the property's formerly open areas.  On the southern edge of the area lies Mount Creek; its drainage, aided by beavers, is the primary wetland for the area.  Ware Creek, at the north end, is another major water source, and the tributaries of both streams may also be seen on the property. Eulithis diversilineata, the lesser grapevine looper, is a moth in the family Geometridae.  The caterpillars are known to feed on Virginia creeper. Parthenocissus quinquefolia, known as Virginia creeper, Victoria creeper, five-leaved ivy, or five-finger, is a species of flowering plant in the grape family, Vitaceae.  It is native to eastern and central North America, from southeastern Canada and the eastern United States west to Manitoba and Utah, and south to eastern Mexico and Guatemala. Parthenocissus vitacea (syn.  "P. inserta"), also known as thicket creeper, false Virginia creeper, woodbine, or grape woodbine, is a woody vine native to North America, in southeastern Canada (west to southern Manitoba) and a large area of the United States, from Maine west to Montana and south to New Jersey and Missouri in the east, and Texas to Arizona in the west.  It is present in California, but it may be an introduced species that far west. Eudryas grata is a moth known as the beautiful wood nymph.  The caterpillars are known to feed on the Virginia creeper ("Parthenocissus quinquefolia"). Darapsa myron (Virginia creeper sphinx) is a moth of the family Sphingidae.  It lives from Maine south to south Florida; west to North Dakota, Nebraska, New Mexico, and Texas.  It also can be found in Mexico.  There are 2 or 3 broods in much of the range, and larvae can mature in as few as 3 weeks.  Larvae hide on the midribs of their host leaves and are nocturnal feeders.  During July and August, this species is abundant in many areas, particularly Massachusetts and Pennsylvania.  Adults emerge in the mid-afternoon and females begin calling after dusk.  In spring, adults are more likely to feed, nectaring from flowers and drinking fluids from rotting fruit.  In areas where they are common, D. myron readily come to both lights and sugar baits, being most active between sunset and midnight.  Females have much rounder abdomens while the end of the male's abdomen is spade-shaped.  Pairing is fairly quick and captive adults do not need to be fed, although females lay more eggs when fed.  Sometimes adults refuse food altogether. Whitetop is an unincorporated community in Grayson County, Virginia, United States.  It is the southern terminus of the Virginia Creeper Trail.  Whitetop is named for nearby Whitetop Mountain, the second-tallest independent mountain in the State of Virginia, behind Mount Rogers.  The town is about four miles northeast of the North Carolina–Tennessee–Virginia Corners. Whitetop Mountain is the second highest independent mountain in the U.S. state of Virginia, after nearby Mount Rogers.  It is also the third highest named peak in Virginia, after Mount Rogers and its subsidiary peak, Pine Mountain.  It is located at the juncture of Grayson, Smyth, and Washington Counties, and is also within the Mount Rogers National Recreation Area of the Jefferson National Forest.  Whitetop was the location of the White Top Folk Festival from 1932 to 1939, with the exception of 1937.  Like nearby Mount Rogers, it represents an ecological "island" of flora and fauna commonly found much further north than Virginia, such as old growth red spruce and other northern softwoods.
