Editing Pollination (section)

=== Examples of affected pollinators ===
The most known and understood pollinator, bees, have been used as the prime example of the decline in pollinators. Bees are essential in the pollination of agricultural crops and wild plants and are one of the main insects that perform this task.<ref name=":6">{{cite journal | vauthors = Potts SG, Biesmeijer JC, Kremen C, Neumann P, Schweiger O, Kunin WE | title = Global pollinator declines: trends, impacts and drivers | journal = Trends in Ecology & Evolution | volume = 25 | issue = 6 | pages = 345–53 | date = June 2010 | pmid = 20188434 | doi = 10.1016/j.tree.2010.01.007 | bibcode = 2010TEcoE..25..345P | citeseerx = 10.1.1.693.292 }}</ref> Out of the bees species, the honey bee or ''[[Western honey bee|Apis mellifera]]'' has been studied the most and in the United States, there has been a loss of 59% of colonies from 1947 to 2005.<ref name=":6" /> The decrease in populations of the honey bee have been attributed to pesticides, genetically modified crops, fragmentation, parasites and diseases that have been introduced.<ref name=":8">{{cite journal | vauthors = Fairbrother A, Purdy J, Anderson T, Fell R | title = Risks of neonicotinoid insecticides to honeybees | journal = Environmental Toxicology and Chemistry | volume = 33 | issue = 4 | pages = 719–31 | date = April 2014 | pmid = 24692231 | pmc = 4312970 | doi = 10.1002/etc.2527 }}</ref> There has been a focus on neonicotinoids effects on honey bee populations. Neonicotinoids insecticides have been used due to its low mammalian toxicity, target specificity, low application rates, and broad spectrum activity. However, the insecticides are able to make its way throughout the plant, which includes the pollen and nectar. Due to this, it has been shown to effect on the nervous system and colony relations in the honey bee populations.<ref name=":8" />

[[Butterfly|Butterflies]] too have suffered due to these modifications. Butterflies are helpful ecological indicators since they are sensitive to changes within the environment like the season, altitude, and above all, [[human impact on the environment]]. Butterfly populations were higher within the natural forest and were lower in open land. The reason for the difference in density is the fact that in open land the butterflies would be exposed to desiccation and predation. These open regions are caused by habitat destruction like logging for timber, livestock grazing, and firewood collection. Due to this destruction, butterfly species' diversity can decrease and it is known that there is a correlation in butterfly diversity and plant diversity.<ref name=":1">{{Cite journal |last1=Humpden |first1=Nyamweya N. |last2=Nathan |first2=Gichuki N. | name-list-style = vanc |date=2010-06-01 |title=Effects of plant structure on butterfly diversity in Mt.
