General Vitaceous Tangles
Habitat Overview The tangles of wild grapes that greeted the Vikings and other early European visitors to North America left quite an impression on them. The Muscadine, or Scuppernong, is particularly entwined in North Carolina history: Governor Ralph Lane, when describing North Carolina to Sir Walter Raleigh, stated that "We have discovered the main to be the goodliest soil under the cope of heaven, so abounding with sweet trees that bring rich and pleasant, grapes of such greatness, yet wild, as France, Spain, nor Italy hath no greater..." (Wikipedia, accessed 2019-10-09).

Muscadine itself grows from the barrier island to the low mountains, and in a variety of open and forested habitats. Weakley (2015) lists: dry upland forests (especially sandy or rocky), other forests, swamps, dunes, roadsides, thickets. Other members of this family are likewise widespread in the state, occupy a wide range of habitat conditions.

Collectively, members of the Vitaceae support a rich fauna of obligate herbivores, most of which feed on several genera but with a few that are more specialized. With the possible exception of Pandora intermedia -- which may be only a migrant in North Carolina -- these species do not appear to be geographically restricted and probably occupy all areas where members of the Vitaceae occur.

Candidates for Inclusion Melanoplus nigrescens, a flightless grasshopper, is frequently found near Muscadine tangles on ridgetops in the Uwharries where almost no other foliage is located close to the ground. Whether or not it actually feeds on Muscadine, let alone whether it is a specialist on it, remains to be determined.

The larvae of Cacotherapia unipuncta, a micro-moth, have been observed feeding on grape mealybugs but it is unknown if either species is strongly associated with native grape species.
