Editing Piophilidae (section)

==Medical and forensic significance==
If swallowed (whether accidentally or otherwise), the larvae sometimes survive in the [[intestine]]s and pass through the digestive system alive. Such behaviour is known as [[enteric]] or [[intestinal]] [[myiasis]]. In the gut, the larvae may cause serious lesions by attempting to bore through the intestinal walls. Symptoms include [[nausea]], [[vomiting]], pain in the abdomen, and bloody [[diarrhea]]. Both living and dead larvae may pass in the [[feces|stool]].<ref name="WarrellCox2003">{{cite book|author1=David Alan Warrell|author2=Timothy M. Cox|author3=John D.

In [[forensic entomology]], the presence of ''P. casei'' larvae may be useful in estimating the date of death for human remains because they do not take up residence in a corpse until three to six months after death.<ref>{{cite web | title=Discovery Channel: You're on the Case | url=http://dsc.discovery.com/fansites/onthecase/toolbox/tool_05.html | access-date=14 November 2005 |archive-url = https://web.archive.org/web/20060316000328/http://dsc.discovery.com/fansites/onthecase/toolbox/tool_05.html <!-- Bot retrieved archive --> |archive-date = 16 March 2006}}</ref> However, ''P. casei'' is not the only piophilid species to attack human corpses, so caution is appropriate in identification of the species found and in interpretation of their significance.<ref name="Gennard2012"/><ref>{{Cite journal |last=Martín-Vega |first=Daniel |date=2011-10-10 |title=Skipping clues: Forensic importance of the family Piophilidae (Diptera) |url=https://linkinghub.elsevier.com/retrieve/pii/S0379073811002970 |journal=Forensic Science International|volume=212 |issue=1–3 |pages=1–5 |doi=10.1016/j.forsciint.2011.06.016|pmid=21802229 }}</ref>
