† Populations may not be currently present.
Means of Introduction: Pet releases.
Status: Reported in Virginia.
Impact of Introduction: Negligible since the species is not established in Virginia (Mitchell, 1994; Ernst et al., 1997). Because G. pseudographica is omnivorous, eating mollusks, insects, crayfish, aquatic plants and more, an established population could influence the food web (Ernst et al., 1994).
