Determination of the time of death is an integral part of any investigation. It is a difficult and complex process, and quite often impossible. There is one more problem: the bigger the interval between the death time and the body found, the more inaccurate will be the estimation. One of the factors used in estimating the time of death is environmental markers, particularly insect activity. A study that investigates insects and uses them to provide more information about crimes is called forensic entomology. Insect activity may give a clue of how long an individual has been dead. Entomologists may identify an approximate time of death by determining “what insects have preyed on the body and at what stage in their development they are at in their progress from egg to adult” (DiMaio & Dana, 2006, p. 27). One of such insects is a blowfly. A blowfly is a carrion-breeding species of medical and forensic importance (Alvarez Garcia, Rérez-Hérazo, & Amat, 2017). In a forensic sense, blowflies can colonize decomposing bodies, and their larvae have been found in human corpses. The typical life cycle consists of 4 stages: egg, larva, pupa, and adult (Rutty, 2013). Dead animals attract adults, and female flies deliver their eggs on the carcass. Blowflies sometimes mistake the necrotic wound of a corpse for a food source and lay their eggs there. It is called wound myiasis (Rutty, 2013). At room temperature in less than a day, the eggs hatch, and the newly appeared wormlike larvae, called maggots, secrete digestive enzymes into the surrounding environment and start to absorb liquefied necrotic tissue (Rutty, 2013). During this stage they pass through various instar stages: 1 st Instar – 5 mm long after 1.8 days; 2 nd Instar – 10 mm long after 2.5 days; 3 rd Instar – 14-16 mm after 4-5 days. They feed for 2–5 days, and then they leave the host and try to find a concealed, secured spot to pupate. Within puparium in less than 3 weeks, they turn into adult flies, leaving an empty pupal case behind as evidence (Rutty, 2013). The common blowfly life cycle in warm weather lasts for 2.5-3 weeks. Bansode, More, and Zambare (2016) conducted research to find out how temperature and humidity affect the blowfly life cycle. It turned out that low temperatures and low moisture conditions increase the duration to complete the life cycle, while high temperatures and high humidity conditions decrease the time needed for it and insects grow faster (Bansode et al., 2016). Thus, to provide a more accurate estimation of time since death, entomologists should take into account the history of surrounding temperature and moisture in the location where the body was found. When the time of death is in question, forensic entomologists undertake several actions to collect samples. First of all, proper equipment is crucial for the accurate collection of data. Preconfigured Forensic Entomology Kits are usually used for such purposes. Nevertheless, several police departments cannot buy ready-made collection kits due to the lack of budget. Entomological collection equipment contains about 20 names of necessary instruments and materials. They include, for instance, aerial insect nets, vials,
