If flies are fed serotonin, they are more aggressive; flies depleted of serotonin still exhibit aggression, but they do so much less frequently.<ref name="Dierick">{{cite journal | vauthors = Dierick HA, Greenspan RJ | title = Serotonin and neuropeptide F have opposite modulatory effects on fly aggression | journal = Nature Genetics | volume = 39 | issue = 5 | pages = 678–682 | date = May 2007 | pmid = 17450142 | doi = 10.1038/ng2029 | s2cid = 33768246 }}</ref> In [[Dipteran crop|their crops]] it plays a vital role in digestive motility produced by contraction.
