An aquatic to amphibious plant forming submerged or emergent meadows with knotty stems that can reach 3 to 4 meters in length and a few millimeters in diameter. This species thrives in slow-moving or stagnant waters, preferably well-lit and shallow (up to a maximum depth of 3 meters).
The brown marmorated stink bug (Halyomorpha halys) is a polyphagous pest native to Asia. It measures between 12 and 17 mm in length and 7 to 10 mm in width, and it is recognizable by the light-dark pattern on its antennae.
The brown marmorated stink bug is also known for occasionally invading homes in large numbers during autumn as it seeks shelter to overwinter.
The brown marmorated stink bug is a hemipteran insect from the Pentatomidae family. The flattened part (connexivum) that extends laterally from the abdomen features alternating light rectangular spots and black spots. On its underside, the abdomen lacks a ventral tip (unlike the mottled shield bug, with which it is often confused).
In France, the brown marmorated stink bug reproduces once a year, with reproduction occurring in summer. The female lays 27–28 eggs, which hatch 3 to 6 days after oviposition (egg deposition on a surface). There are five larval stages before reaching adulthood. The brown marmorated stink bug is a polyphagous piercing insect that feeds on fruits (apples, cherries, peaches, raspberries), vegetables (tomatoes, eggplants, peppers), and ornamental plants (butterfly bush, hibiscus).
The African Clawed Frog (Xenopus laevis) is an amphibian from the Pipidae family. Its body is flattened and smooth, gray-brown marbled with black spots, with lateral seams on its sides, throat, and belly. Its eyes are positioned on top of its head, and it lacks a tympanum. Highly aquatic, this species can also move on land for several hundred meters.
Adults hibernate in the mud at the bottom of the water.

A species that is indigenous or non-native to a given territory, proliferates and extends its range due to an increase in population density.
Any live specimen of a species, subspecies or lower taxon of animals, plants, fungi or micro- organisms introduced outside its natural range; it includes any part, gametes, seeds, eggs or propagules of such species, as well as any hybrids, varieties or breeds that might survive and subsequently reproduce.
