The carnivorous plants of the Droseraceae family include a huge list of plants. The plants of this family have their leaves disposed in a rosette-like way. These leaves are modified to make it possible for the plant to capture small insects, and it is usually covered by some sort of fur that produces a sticky substance called mucilage.

The process of capturing insects starts by attracting them to the plant's leaves. To do so, many species use the same tactics as flowers: leaves with lively colors, nectar odor or ultraviolet light reflection patterns.

Once attracted, the insects are captured. For this, the carnivorous plants developed some structures that work as traps. They may work like a cage, on species of the Dionaea genus (occurring in North America) in which the leaves are divided in two parts that close themselves, imprisoning the prey.

They may as well capture their victims by suction, like the species of the Utricularia genus, which have vesicles that suck and imprison the victim. Another way is to make use of sticky leaves like the Drosera brevifolia that can be found in Brazil.
