Endemic to Madagascar, Nepenthes madagascariensis (Caryophyllales - Nepenthaceae) is listed as Vulnerable species on the IUCN Red List. This pitcher plant can be found along the edges of swamps and in peaty/sandy soils at low altitudes.
The pitcher of this species are visited by a wide variety of insects attracted to the bright color of the pitcher, the nectar secreted around its opening, and the odor of the fluid. The insect visitors appear to become disoriented over time and with increasing likelihood fall into the pitcher and drown.
The pitchers form a temporary habitat functional for about three months. Several specialized arthropods including mosquito larvae, mites, and fly larvae complete their life cycle in the pitcher and depend directly or indirectly on the drowned insects falling into the pitcher.
Nepenthes stenophylla (Nepenthaceae) is a spectacularly colored species of pitcher plants covered in small hairs. In the wild it grows to about 3m in height with multiple branching stems. A large plant of this species is truly spectacular.
