Dear melbell-ga,

Your questions relates to Forensic Entomology: the study of insects,
applied to forensics. The study of insects found in a dead body can
help to ascertain the time of death and place of death.

Neal Haskell is a forensic entomologist; he has written an article on
the subject and part of it answers your question. It is available only
through the Google cache.

"Blow flies are usually the first insects to attack human remains and
begin colonization.  The only access into the underlying soft tissues
of the body for adult human corpses is through the nine natural body
orifices. The nose, mouth and eyes of the face are most attractable.
They have moisture, protection, and provide access to the underlying
soft tissues such as muscle or internal organs.
Of these openings on the face, the nose and mouth discharge the odors
that are highly attractive to flies? very acute sense of smell.
Additionally, the mucus membranes of these areas provided easy access
to the newly hatched first stage maggots that need to begin feeding
immediately after hatching."

These other web sites may also be of interest.

"On fresh corpses, look for these clumps in the mouth, in nasal
openings, in the ears, and generally in any area where mucus membranes
come into contact with the outside air."

"Blowflies usually select natural body openings for oviposition (eyes,
nostrils, ears, mouth, and less so at anus and genitals) but will
preferentially lay eggs on any wounds that may be present."
