Post Mortem Interval Estimation
One of the key characteristics of using blow flies in developing a post mortem interval estimate is the succession of insects that colonize the body. Based on the insects present at the time, a reasonable time frame for death may be established. C. vicina has its own part in the succession of the corpse.
C. vicina plays a major role in corpse colonization during the winter months, with less of a presence during the warmer months when temperature is less of a constraint. This fly has a lower threshold temperature for flight activity than other blow-flies, allowing for greater prevalence during colder periods. This period of activity must be considered when evaluating the presence or absence of this fly.
When using the age of maggots to determine the PMI, the time before arrival is an important factor. The succession of C. vicina involves the arrival of adults two days after death. Therefore, two days must be added to the maximum age determined for flies found on the body.

Famous quotes containing the words post, interval and/or estimation:
“I had rather be shut up in a very modest cottage, with my books, my family and a few old friends, dining on simple bacon, and letting the world roll on as it liked, than to occupy the most splendid post which any human power can give.”
—Thomas Jefferson (1743–1826)
“The yearning for an afterlife is the opposite of selfish: it is love and praise for the world that we are privileged, in this complex interval of light, to witness and experience.”
