Sundew

Photo taken by Idelle in Bishop's Bog

This, here, is a picture of Drosera, also known as "Sundew." Specifically, it is a "temperate sundew" which lives in North America as well as Europe. Most of the other types (up to 194 different species) of sundews live in Australia. The sundew is a carnivorous plant that secretes sweet substances in order to attract small insects. The sweet secretion is also sticky, trapping the insect and clogging it's airways, causing it to suffocate within 15 minutes. Once the fly is caught, the plant releases enzymes that decompose the fly. The plant then uses the decomposed fly as nutrients for itself. This is necessary for the plant because many sundews live in environments in which there are few nutrients in the soil. 


Other fun facts!: 
  • The sundew is also used as an herbal remedies for bronchial illnesses such as coughs. 
  • Sundews are popular ornamental plants, also serving as an insect reducer in households
  • Sundews are more widespread than Venus Fly Traps, and have more species than any other carnivorous plant
