Editing Pitcher plant (section)

=== Attraction ===
Foraging, flying, or crawling [[insect]]s such as flies are attracted to a cavity formed by the cupped leaf, often by visual lures such as [[anthocyanin]] pigments, and [[nectar]]. Many pitcher plants exhibit patterns of ultraviolet coloration which may play a role in attracting insects.<ref name=":0" /> Some species, such as ''Cephalotus follicularis'', likely use camouflage to trap insects, as their coloration matches that of the surrounding environment and the plants are often embedded in the substrate such that the traps are flush with the ground.<ref name=":0" />

Olfactory cues can also play a role in attraction. For example, ''Nepenthes rafflesian''a uses flower-scent mimicry to attract insects to its pitchers.<ref>{{Cite journal |last1=Di Giusto |first1=Bruno |last2=Bessière |first2=Jean-Marie |last3=Guéroult |first3=Michaël |last4=Lim |first4=Linda B.
