'''Hypodermyasis''' is a [[parasitic]] [[infection]] by the [[larvaelarva]]e of [[Warble fly|warble flies]], most notably ''Hypoderma lineatum'' and ''Hypoderma bovis''. These flies mostly infect [[cattle]] in the warmer areas of the [[northern hemisphere]]. Humans become hosts when they inadvertently swallow the eggs of those flies.<ref name='wd'> {{cite web|url=http://www.wrongdiagnosis.com/h/hypodermyasis/intro.htm#whatis |title=Hypodermyasis |accessdate=2009-03-28 }}</ref>
