Toxorhynchites
Toxorhynchites, also called elephant mosquito or mosquito eater, is a genus of diurnal and often relatively colorful mosquitoes, found worldwide between about 35° north and 35° south. It includes the largest known species of mosquito, at up to in length and in wingspan. It is among the many kinds of mosquito that do not consume blood. The adults subsist on carbohydrate-rich materials, such as honeydew, or saps and juices from damaged plants, refuse, fruit, and nectar.
Färnebofjärden National Park
The species of insect most associated with the park and the Lower Dalälven in general are mosquitos of the genus "Aedes". Indeed, the park's wetlands are enormously productive in mosquitos, especially during the heavy spring floods. The quantity of mosquitos in the Lower Dalälven has no equivalent in Sweden besides that in the vast wetlands of Lappland. This abundance bothers not only the park's tourists during the summer but also the entire region as far as Uppsala. Between 2002 and 2008, the insecticide was used to try to regulate these populations, which needed a waiver, its use being forbidden in Sweden and contrary to the principles of the national park. However, the project was not renewed, this method not being considered a durable solution and some scientists arguing that the mosquitos make up part of the region's ecosystem.
