§1

Range & habitat

The indigenous distribution of Pomacea haustrum is Bolivia, Brazil and Peru in South America. The nonindigenous distribution includes the United States: Loxahatchee National Wildlife Refuge waters in Palm Beach County, Florida. Pomacea haustrum were discovered in the late 1970s in Palm Beach County Florida, and have not spread appreciably in 30 years. This is the only known area where this species is established in the United States. The initial introduction in the United States was probably from aquarium release, aka "aquarium dumping". Pomacea haustrum is currently of relatively minor concern in the U.S., given its failure to spread beyond Palm Beach County after 30 years or more in Florida. However, many species have maintained limited distributions, sometimes for decades, before becoming invasive.

What it does

Populations of Pomacea haustrum in Florida produce bright green egg masses consisting of individual eggs approximately 3–5 mm in size compressed into polygonal shapes, giving the egg mass an irregular honeycombed appearance. Since other Pomacea species also produce green eggs, this character is insufficient to verify this species as Pomacea haustrum. It lays its eggs in clutches above the water level.
