Basic Description: Perennial, insectivorous, scapose herb; 10 to 30 cm tall (Kral 1983). 莲座叶从收缩的茎向四面八方展开, with broad, 扁平的叶柄(叶茎)，刚好在叶片下面收缩(Kral 1983, Russo 1993). 叶片高度改良，类似捕熊器, with the midrib acting as a hinge and the edges with stout marginal bristles used to trap insects once the tactile hairs near the midrib are activated (Kral 1983, Russo 1993). 叶片的上表面颜色从绿色到鲜红色不等(Kral 1983). Inflorescences of few to several flowers at the summit of a slender scape; petals are white in color, 有明显的绿色脉纹(Kral 1983). 种子是黑色和有光泽的, 一旦成熟的胶囊打开，就会暴露出来(Kral 1983, Weakley 1996).

Preliminary Genetic results from the 2017 Study conducted by Johnny Randall and colleagues revealed the following: (1) Restriction site-Associated DNA sequencing (RAD-seq) of 160 markers indicate limited genetic variation within the first population sampled. (2) Genetic variation was surprisingly heterogeneous across loci with some populations harboring appreciable variation and others harboring next to none. (Randall et al. 2018)
In 2017, 约翰尼·兰德尔和同事们收集了超过26个,415 seeds from 20 sites all by maternal line (other than bulk collection) - vacuum-sealed and frozen. (Randall et al. 2018)
捕蝇草是一种在园艺贸易中广泛交易的物种. 偷猎仍然是一种威胁. Plants growing alongside roadways are especially vulnerable due to potential herbicide exposure. The construction of a highway will most likely cause the small population located in South Carolina to slip into extinction. (Randall et al. 2018)
The NatureServe global rank of Venus fly trap was changed from vulnerable (G3) to imperiled (G2) in 2018 to reflect declining population sizes and continued poaching threats. Currently there is a petition in place submitted by Don Waller of University of WI to upgrade to Endangered or Threatened. (Randall et al. 2018).
Upcoming 2018 study to be conducted by Johnny Randall and colleagues with specific aims: (1) Sample 150 VFT populations across the existing range for both tissue and seeds and create a long-term seed bank as a conservation resource. (2) Evaluate standing genetic variation in 40 select populations using restriction site associated DNA sequencing (Next Generation RAD-seq.). Special emphasis will be placed on collecting from private lands rather than public lands as was performed in the 2017 study. 此外，还必须进行一项新的状态调查. (Randall et al. 2018)
In 2017, Mike Kunz and colleagues at North Carolina Botanic Garden conducted a study of pollinators of the Venus fly trap. They found that bees, beetles, and flies are the dominant pollinator species (Youngsteadt et al. 2018).

Venus fly trap is typically found in the wet pine savannah of North Carolina (Randall et al 2018). 在更常见的外海岸平原， Dionaea muscipula occurs in broad ecotonal areas between Pine Savannas or Wet Pine Flatwoods and pocosins (evergreen shrub bogs). 这些地点通常平坦，一年中的大部分时间都是潮湿或潮湿的土壤. 这种物种很少出现在季节性洪水泛滥的洼地, 尽管它可能发生在这些地点的边缘. In the Sandhills region, it is limited to narrow, 流水头波科辛之间的潮湿交错区(线性, evergreen shrub bogs along small creeks and their headwaters) and longleaf pine/scrub oak/wiregrass uplands and along the vegetatively similar ecotones between Sandhill Seeps and longleaf pine uplands. 沙丘渗水是灰蒙蒙的, shrub-and-herb-dominated areas occurring in relatively steep places where local clay soils force seepage water to the surface. 这些生态区的土壤通常是高酸性的壤质砂.
