Occurrences Comments

Hubricht (1953) lists vacant lots in Norfolk, Norfolk Co., Virginia. It has also been reported by Pilsbry (1939) from Charleston, South Carolina, Baton Rouge and New Orelans, Louisiana, and numerous areas in coastal southern California. Inland reports include Santa Fe, New Mexico (Cockerell, 1936), Shreveport, Louisiana (Branson, 1961), and Boulder, Colorado (McCoy and Nelson, 1962). It was first introduced to Hawaii in 1952 and 1956 in Oahu, on the Island of Hawaii in 1976, and from Maui (Kula) in 1981 (Cowie, 1996). A new record was found in Virginia in the city of Chincoteague, Accomack Co. (Orstan, 2008). Previous Virginia records include "near Virginia City" in 1924 (Dundee, 1974), Norfolk in 1943 (Hubricht, 1971), and in Chesapeake Co. (Beetle, 1973).
