Drosera – the Sundews

TRAP TYPE: Flypaper Trap
Currently Ca. 152 listed species occupying temperate and tropical habitats throughout the world.

The master of sticky fly paper, Drosera (sundew), is a slow trap compared to the one in Venus Flytrap. However, the sundew relies on first trapping its prey with its sticky, glandular hairs, as shown in Figure 1, before it slowly rolls up the edges of the leaf. It does not fold like the Venus fly trap, but it can effective enclose small flies with the numerous hairs.

The sundews, so named because their glandular leaf hairs glisten like dew in the sun, are not only common in bogs, but can occur on sandy banks and other mineral soils poor in organic nitrogen and phosphorus. So fascinating is this tiny plant that Darwin (1875) spent 285 pages of his book on insectivorous plants describing his own experiments on it.
