“…The rainfall four weeks prior to the trap date had a significant positive effect on L. sericata numbers. This finding is supported by research showing L. sericata colonizes carcasses in water (along with only Cochliomyia macellaria and Sarcophaga bullata) [64], and the species' ability to survive submerged in water as pupae is longer than C. vicina [65] and C. vomitora [66]. Lucilia sericata numbers fluctuated greatly between the first and second year of the current survey with the second year showing significantly higher numbers of L. sericata, coinciding with a much wetter year.…”

Changes in common and widespread insect populations such as the domestic filth fly in urban cities are useful and relevant bioindicators for overall changes in the insect biomass. The current study surveyed necrophagous flies by placing a weekly trap from June–September over a two-year period in the city of New Haven, Connecticut, to compare data on fly abundance and diversity with data collected 78 years earlier. Climate and land cover changes were also assessed in combination with the fly population for each period. The survey results suggest the domestic filth fly population is now less diverse with decreased species richness and changes in the relative abundance of species. In both surveys, 95–96% of the population was composed of only three species. The current survey data indicate the numerical dominance of Lucilia sericata has decreased, the abundance of several species, notably Lucilia coeruleiviridis, has increased, and Lucilia illustris is absent. Species that showed a significant interaction with temperature in the 1940s survey have now increased in abundance, with several of the trapped species continuing to show an interaction with temperature and rainfall. Analysis of the land cover and climate data characterizes the trap site as a region exposed to a prolonged period of industrialization and urbanization, with only 7% of the land cover remaining undeveloped and over 50% impervious, coupled with an increase in temperature and rainfall. This study serves as a model for changes in domestic filth fly populations and other insects in similarly highly urbanized established cities.

“…The pupa age factor plays an essential role in determining survival with longer soaking periods giving lower survival rates. Magni et al (2021) studied the survival and eclosion of Ca. vomitoria (Linnaeus) (Calliphoridae) and L. sericata intra-puparial forms after submersion in various types of water.…”

Background Understanding how environmental conditions can influence the insect distribution on corpses is essential to determine the postmortem interval. However, literatures related to forensically important flies in an aquatic environment were scarce. We report herewith a case series comprising three forensic cases related to floating corpses infested with fly larvae in Kuala Lumpur, Malaysia. Case presentation Case 1 involved the corpse of a 43-year old male found in the waterside of an abandoned mine. Case 2 was a 40-year-old male floating on a river stream, while case 3 was an 11-year-old boy who was found trapped in a monsoon drain after heavy rain. Numerous larvae of various stages, identified as Chrysomya megacephala (Calliphoridae) species, were collected in all cases even though the number of larvae was relatively lower compared to those usually collected on corpses found on terrestrial areas. Besides, the larvae of Eristalis spp. (Syrphidae), which are known to be exclusively associated with water bodies, were found in two of the cases. The blowfly Ch. rufifacies (Calliphoridae) larvae were collected only in case 3. Conclusions These findings show that both Ch. megacephala and Ch. rufifacies can be found in the ecologically varied death scene habitats including aquatic areas. Meanwhile, the presence of Eristalis spp. can be used as an indicator of death location associated with an aquatic environment. The challenges and limitations of analyzing entomological evidence on bodies discovered in aquatic environments were also discussed.

“…Insects with mobile developmental stages can avoid rising floodwater via escape reactions such as running, climbing, and flying to upland areas or higher vegetation (Adis & Junk, 2002;Batzer & Wu, 2020;Wantzen et al, 2016). Some insects with less mobile or sessile developmental stages can survive inundation for several hours to several months (Brust et al, 2005(Brust et al, , 2007Brust & Hoback, 2009;Cavallaro & Hoback, 2014;Clark & Richmond, 1962;Forschler & Henderson, 1995;Hoback, 2011;Hoback et al, 1998Hoback et al, , 2002Joy & Pullin, 1997;Kolesnikov et al, 2012;Kölsch, 2001;Kovalev et al, 2020;Li et al, 2019;Mądra-Bielewicz et al, 2017;Magni et al, 2021;Nielsen & Christian, 2007;Reigada et al, 2011;Singh & Bala, 2011;Singh & Greenberg, 1994;Tamm, 1984;Webb & Pullin, 2002;Wyatt, 1986;Yee, 2021;Zerm & Adis, 2001). Temporal inundation is expected to affect the population growth rate and distribution of insect populations.…”

Submergence tolerance in immature stages of the stalk‐eyed fly Sphyracephala detrahens (Diptera: Diopsidae)

Sphyracephala detrahens (Walker, 1860) (Diptera: Diopsidae) inhabits the riparian zones of streams and rivers. Because of the limited dispersal ability of S. detrahens during egg, larval, and pupal stages, immature individuals are at risk of being submerged by floodwater after heavy rain. In this study, I evaluated the submergence tolerances of immatures of S. detrahens by comparing them to immatures of Drosophila melanogaster, which also feed on rotten fruits but are not restricted to the riparian zone. The results showed that S. detrahens eggs were susceptible to desiccation, but more than 80% of eggs hatched after full submergence. Later instar larvae were more resistant to full submergence than earlier instar larvae. The duration of submergence causing 50% pupation (PD50) in the first, second, and third‐instar larvae of S. detrahens were 15.88, 58.46, and 91.74 h, respectively. The PD50 of the third‐instar larvae of D. melanogaster was 20.01 h. Third‐instar S. detrahens larvae continued to develop in water for a longer duration than D. melanogaster larvae of the same instar. In the pupal stages, late pupae tended to remain afloat longer than early pupae. The duration of submergence causing 50% emergence (ED50) of adults from early and late pupae were 40.70 and 104.74 h, respectively. In the larval and pupal stages, individuals in the later developmental phases tended to be more tolerant to full submergence. The submergence tolerance of the immature stages of S. detrahens may reflect adaptation to an environment with fluctuating water levels.
