Sundews and butterworts
have what's known as flypaper/adhesive traps, while pitcher plants use pitfalls, and bladderworts, as their name suggests, use water-filled bladder traps.
In Insectivorous Plants, Darwin (1900) made reference numerous times to the pollen grains, leaf fragments, and seeds found on the sticky leaves of sundews and butterworts
Other passive trappers, like Manitoba's two butterworts
(Pinguicula vulgaris & P.
On the negative side, a long period without grazing may have been too much for our tiny colony of butterworts
- we could not find any this year.
The case is much the same with other species of insectivorous plants, including the Venus' fly-trap, butterworts
, and bladderworts, which Darwin discussed far more briefly.
D'Amato also grows butterworts
, which secrete a sticky substance that acts like flypaper, gluing its victims in place as enzymes (proteins that aid body functions) digest the insect's soft tissues.
