Abstract		Background: Forensic entomology is a study of insects and arthropods, which can be found on carcass with purpose to estimate postmortem interval. Insects are the first to arrive on the carcass and colonize it in predictable waves. Blowflies are first colonizers of the body, mainly of the folowing genera: Gucilia, Calliphora and Phormia. Then follow flies of the family Sarcophagidae. Piophilidae colonize the carcass after the carrion is totally removed. There is a major diference between fly families in seasonal activity, time of egg laying, hatch time, interval and place of puppating and emerging of flies. The next important succession wave represent beetles , mainly from families Silphidae, Staphylinidae, Cleridae and Histeridae. Aims: Recent researches show that egg laying, hatch, growth, puppating and emerging of new flies is temperature and species dependent. Most of the researches were conducted in laboratory conditions at constant temperatures, only few with fluctuating temperatures. Natural environment is constantly changing. We were observing secondary postmortem changes, which were caused by insects on a pig carcass (Sus scrofa scrofa L.). Our aims were: (1) To observe seasonal activity of flies. (2) To estimate the hatch time and draw growth curves for larvae. (3) To estimate the depth of larval invasion in internal organs and to describe individual diferences. (4) To estimate the loss of carcass mass in correlation with time. (5) To estimate the rate of carcass cooling. Hypothesis: Our hipotheses were: (1) Developmental intervals will be longer in natural environmental than in laboratory conditions. (2) On the carcass we will find the eggs of the same fly family, as were found in neighbouring regions. (3) We will find eggs of different fly families on a same carcass. (4) On all carcasses, which will be exposed at the same time will dominate the flies of the same family. (Abstract truncated at 2000 characters)
