The Venus flytrap, a small perennial herbaceous plant, is one of the most widely recognized carnivorous plant species on Earth. It occupies distinct longleaf pine habitats in the Coastal Plain and Sandhills of North Carolina and South Carolina. In the late 1800s, Charles Darwin conducted research on the plant, calling it “one of the most wonderful plants in the world.” In 2023, the U.S. Fish and Wildlife Service determined that the species does not meet the definition of threatened or endangered, and listing is not warranted under the Endangered Species Act.
The main threat to the species is habitat loss, especially in the form of fire suppression, conversion to agriculture and silviculture and development. Fire suppression is also an important threat, leading to shrub and tree encroachment and a gradual decline in the quality of Venus flytrap habitat. Agriculture and silviculture often include clear-cutting trees and bedding the soil in order to grow crops or trees. Development may include cutting trees, ditching, and draining wetlands and building structures in suitable habitat. Roadside occurrences of Venus flytraps are threatened by road maintenance, vegetation management and road expansions. Poaching is another threat to Venus flytraps. Over the years, Venus flytrap plants have been taken from the wild for the horticulture trade and use in pharmaceuticals. Poaching Venus flytrap plants became a felony in North Carolina in 2014.
In October 2016, the Service was petitioned to list Venus flytrap as an endangered species under the Endangered Species Act. Updated information on Venus flytrap’s status was published in the Federal Register in December 2017, along with a “warranted” 90-day finding and notice initiating a Species Status Assessment. A “warranted” finding indicates the petition contained substantial information indicating listing may be warranted for the species. The Service funded a status survey of the species conducted in 2021 and 2022 which informed decision makers about the status of the species.
In 2023, the U.S. Fish and Wildlife Service determined that the species does not meet the definition of threatened or endangered, and listing is not warranted under the Endangered Species Act.
Venus flytraps produce white flowers from May through June with fruits maturing June through July.
Venus flytraps reproduce sexually through flowering. Vegetative or asexual reproduction occurs from buds that grow from short rhizomes.
While Venus flytraps have survived in cultivation for at least 25 years, their lifespan in the wild is unknown, but probably much shorter.
In addition to the Venus flytrap, North Carolina has more than 30 species of carnivorous plants, including multiple types of Butterworts, Pitcher Plants and Bladderworts. They occur across the state from wet longleaf pine savannas of the coastal plain to mountain bogs. Each genus of carnivorous plant uses a different method for trapping insects. The Venus flytrap, with modified leaves that close forming a trap, is unique in the plant world. There is no other species like it.
Like most plants, the Venus flytrap’s main source of energy is provided through photosynthesis but the digestion of insects gives the plant nutrients that are not readily available in the surrounding environment.
Most carnivorous plants selectively feed on specific prey. This selection is due to the available prey and the type of trap used by the organism. With the Venus flytrap, prey is mostly limited to crawling arthropods (33 percent ants, 30 percent spiders, 10 percent beetles, and 10 percent grasshoppers, with fewer than five percent flying insects). Once prey is trapped, it may take the plant from three to 20 days to gain nutrients before reopening the leaves. According to research conducted at N.C. State University, Venus flytraps don’t trap the insects that pollinate them.
Venus flytrap occupies distinct longleaf pine habitats in the two physiographic regions of the Carolinas - the Coastal Plain and the Sandhills. In the Coastal Plain where it is more common, Venus flytrap occurs in wet longleaf pine savannas. These sites are generally flat with wet or moist soils for much of the year. The plant occurs in ecotones between wet savannas and drier areas such as the sandy rims of Carolina Bays. In the Sandhills region, it is limited to narrow, moist areas between streamhead pocosins (linear, evergreen shrub bogs along small creeks and their headwaters) and longleaf pine/scrub oak/wiregrass uplands and similar areas between Sandhill seeps and longleaf pine uplands.
