The aim of the study was to determine the degradative succession of insect decomposing families. It utilized a descriptive qualitative survey. The study, facilitated by the members of the research team, was conducted on the month of September, in Libi Residence located at 48N, Escario Street, Kamputhaw, Cebu City, Philippines. Twelve raw pork chop meats with skin, fat and bone were bought in Robinson's Mall. It was sealed with plastic cellophane to avoid contamination during transport from the mall to Libi Residence.

                In this study, it was found that, the succession of insect decomposing on the pieces of raw pork following the standard pattern as outlined in the conceptual framework. The insect decomposing families started from Calliphoridae family of flies since Calliphoridae is a primary scavenger that is why they were dominant in our findings. They are the ones that attack first due to their mechanical and chemical factors that help them penetrate on the tissue of the decayed flesh. Maggots of flies for the 1st 9 days belonged to Calliphoridae. Temperature doesn't have effect on the degradative process.  Whether a high or low temperature, insect decomposing family was still effective.

The family Calliphoridae is a primary scavenger due to their mechanical and chemical factors that help them penetrate on the tissue of the decayed flesh, that is why they were dominant in our finding.  Other families didn't flourish because resources weren't available for them. For effective study, this time using a whole dead pig as the experimental organism and conduct separate experiments to determine the effect of temperature variations on the development of the larvae of insect decomposers.
