Taxonomy
Order: ARANEAEInfraorder: AraneomorphaeFamily: Araneidae                                                                                 
Comments: First described in 1833 as Epeira mexicana by Lucas, that name was sunk as nomen oblitum in 1976, so it took the specific epithet from Walckenaer in 1841, when he described it as E. arenata. It was moved to the genus Verrucosa by McCook in 1888.
Species Comment: Several regional, colloquial names have been used to describe this spider, including "triangulate orb weaver" and "arrowhead spider."

Habitats and Life History
Habitats: forest edge, forest
Observation Methods:
Abundance/Frequency: Fairly common in the mountains and Piedmont--less so in the Coastal Plain.
