Nature Minute: Carnivorous plants in local bogs

A Nature Minute about pitcher plants and sundews-both are carnivorous plants that live in our local bogs. The acidic conditions in these bogs limit nutrient availability-an adaption to this is to supplement nutrients from the soil with nutrients from insects.

The sticky hairs on these tiny sundews trap insects. The digestion takes place further down the stem. The sticky hairs are projections of the leaves. Each is tipped with a sticky gland that produces droplets that look dew glistening in the sun-hence the name. The sticky stuff is nectar that attracts prey but is also an adhesive that traps it as well as digestive enzymes to eat it. They eat a lot of mosquitos and other flying insects. They can kill an insect in 15 minutes!!!

The pitcher of a pitcher plant-traps mostly slow moving ground-crawling insects. Insects explore the pitcher, slide into the digestive-juice containing water trapped in the pitcher and can’t get out. A grisley death!
