Editing Pitcher plant (section)

=== Capture ===
The rim of the pitcher (peristome) is slippery when moistened by condensation or nectar, causing insects to fall into the trap. The walls of the pitfall may be covered with waxy scales, protruding [[aldehyde]] crystals, [[Plant cuticle|cuticular]] folds, downward-pointing hairs, or guard-cell-originating [[wikt:lunate|lunate]] cells, to help prevent escape.<ref name="Krol-etal-2011" /> The small bodies of liquid contained within the pitcher traps are called [[phytotelmata]]. They drown the insect, whose body is gradually dissolved. This may occur by bacterial action (the bacteria being washed into the pitcher by rainfall), or by digestive [[enzyme]]s secreted by the plant itself. Pitcher trap fluids largely vary in their viscoelasticity and acidity, which then dictates which type of prey they can target. For example, increased viscoelasticity is associated with increased insect retention to help capture flying insects such as flies, whereas increased fluid acidity can decrease insect killing-time, which can help capture crawling insects such as ants.<ref>{{Cite journal |last1=Bazile |first1=Vincent |last2=Le Moguédec |first2=Gilles |last3=Marshall |first3=David J. |last4=Gaume |first4=Laurence |date=2015-03-01 |title=Fluid physico-chemical properties influence capture and diet in Nepenthes pitcher plants |url=https://doi.org/10.1093/aob/mcu266 |journal=Annals of Botany |volume=115 |issue=4 |pages=705–716 |doi=10.1093/aob/mcu266 |issn=0305-7364 |pmc=4343297 |pmid=25672361}}</ref> Some pitcher plants contain [[Mutualism (biology)|mutualistic]] insect [[larva]]e, which feed on trapped prey, and whose [[excreta]] the plant absorbs.<ref>{{Cite journal | year = 1998
