Can an entomologist, with his expertise, determine how long an individual has been dead?

Answer 1

*IF* the corpse was accessible to insects. If the body is in an enclosed space, and no insect was able ot get to it, then an entomologist expertise is unapplicable.
What a forensic entomologist can do is identify the species of insect present around, on and (*yecch!*) inside the corpse, and, using known insect development rate as a function of the temperature, deduct how long that corpse had been there. Of course, the method has limits, if someone finds a body that has been skeletonized, then the insects have moved away and not much can be gained from an entomologist. But for "fresher" corpse, the method is very reliable and surprisingly accurate, almost down to an hour over a period that can span a week.
But forensic entomology goes far beyond just determining a time of death, as the proposed link will explain.

Answer 2

That depends on whether or not certain insects are decomposing the body. Entomologists just study insects, so without them they can't tell much of anything.

That being said, yes, certain insects appear/lay eggs at certain times, so the hatching of different eggs indicates when individuals were killed, although this can easily be skewed with heating the body, cooling the body, or using similar techniques.

Hope that answers your question.

Answer 3

Yes.

Forensic Entomologists use insects to determine approximate time of death.

Answer 4

simple answer..

flies are made by God for certain purpose..there are alot of species and when sumone is dead..from days to days..different species of flies will come to that corpses..

we cannot find the first day flies on the second day and so the forensic will determine which species of flies inhibit the deceased and so can determine on what day the man had died

Answer 5

Yes.
There is actually a book about forensics like this called "Stiff".
It's fascinating.

Answer 6

Time of death is determined by body termperature.

Answer 7

Robinson's answer is the best you can expect.
