“…Tomberlin and colleagues highlighted that basic ecological and evolutionary experiments are the key for understanding the concept of carrion biology and especially for improving the accuracy and reliability of forensic case work. We believe that the results of our study can likely shed some light on the interpretation of rare cases with delayed colonisation or cases where exposed cadavers are uncolonised even under optimal conditions (Wells, 2019;Wells et al, 2021), but more importantly serve as a grounding for further understanding and quantification of the oviposition behaviour of necrophagous flies in their natural environment.…”

“…A limitation mentioned in that study was that ‘not every female fly on the wing with access to carrion will necessarily guarantee an oviposition’, a point already highlighted by Catts (Catts, 1992). To understand/assess delays in colonisation of cadavers or even no colonisation (Wells et al, 2021), it is essential to monitor not only flight activity but quantify the oviposition activity.…”

1. Locating an optimal oviposition site can be a challenging task for female insects, especially when dealing with a patchy, unpredictable and ephemeral food source such as carrion. Understanding the biotic and abiotic parameters that influence the oviposition behaviour of necrophagous flies is not just of great biological importance but also essential for their application in legal investigations.2. In this study, we monitored the oviposition activity of necrophagous flies (Calliphoridae, Sarcophagidae) using mouse carcasses in an urban (city) and a rural (mixed forest) habitat in Frankfurt/Germany over a 2-year period.3. Over 240 sampling days, 220,963 larvae of 4 blow fly species and 1 flesh fly were sampled. The most abundant species was the blow fly Lucilia ampullacea, followed by its family members Calliphora vicina and Lucilia caesar, the flesh fly Sarcophaga caerulescens and Lucilia sericata. Up to seven environmental parameters were statistically significant predictors for a colonisation of the carcasses, leading to unique patterns of seasonal and daily oviposition activity for all five species. 4. Overall, the analysis showed that the seasonal adaption (the phenology of each species), the habitat (rural vs. urban) as well as temperature are the most important factors influencing the oviposition behaviour and activity of necrophagous blow flies and flesh flies.

“…The reason for the prolonged development in our observation is probably that the larval stages of C. albiceps were suppressed by those of sarcophagid flies. Wells JD et al [22] who monitored the presence of insects and their development stages on exposed rat carcasses saw adults of C. albiceps on the deposited baits but time for the colonization of the rat carcasses with their larvae took longer compared to S. dux and W. nuba.…”

Two species of parasitoid wasps, Brachymeria podagrica (Fabricius, 1787) and Dirhinus himalayanus Westwood, 1836 of the Chalcididae family, hatched from pupae maggots which were deposited by sarcophagid flies on a camel meat bait. While B. podagrica infects maggots, D. himalayanus lay eggs into fly pupae. The preimaginal development of both wasp species under laboratory conditions at 26 to 28 oC lasted 25-28 and 24-33d, respectively. The yield of wasps in four different samples varied between 31 and 83% and the development of Sarcophaga dux and Wohlfahrtia nuba was impeded considerably compared to an unexposed control group. The calliphorid species, Chrysomya albiceps, remained uninfected. B. podagrica and D. himalayanus are potential candidates for a biological control of flies.
