“…All 10 species of the family Calliphoridae, which were present on the bodies, belong among common necrophagous European fauna. The most common species of our dataset was by far C. vicina (69 %), while in some other ecological studies from Switzerland or Germany first place often belongs to L. sericata [ 3 , 12 , 34 ]. In our case, L. sericata was present in 30% of cases (while still being the second-most dominant species of our dataset).…”

“…Even with such a small amount of appearances in the highest altitudes, the affinity to altitude was significant for L. caesar and C. vomitoria as the trend was set in lower altitudes. Calliphora vomitoria is a thermophobic species [ 12 , 39 ], which could explain its altitudinal preferences if we consider elevational gradient as a surrogate of climate [ 38 ]. Indeed, the temperature profile in high elevations will always be one of the limiting factors, which means that thermophilous species will visit higher altitudes only occasionally during the warmest days of the year.…”

“…The seasonal occurrence of blowflies in Europe has already been studied in several experiments (Portugal [50]; Spain [6,48]; England [4]; Germany [34]; Switzerland [12]; Italy [47]). However, the activity of geographically distant populations within the same species can differ due to their local adaptations [51][52][53].…”

“…The common design of experiments, which aims to map the distribution and habitat preference of blowflies, often counts on baited traps usage (bottle traps, inverted cone traps, Schoenly traps) which attract the specimens by using different kinds of attractants [4,[10][11][12][13][14]. The bottle traps certainly can serve as a basic tool for monitoring of blowflies; however, the attractiveness depends on the type of bait used.…”

Necrophagous blowflies (Diptera: Calliphoridae) are of great importance particularly during investigations of suspicious deaths. Many studies have analyzed the distribution of blowflies based on pig experiments and baited trapping; however, data from real case scenarios are rarely used. In this article, the distribution of blowflies found during investigations of 160 real cases during 1993–2007 in Switzerland is evaluated based on habitat, altitude, and season. Ten species of blowflies were present in 145 out of the 160 cases. The most common species was Calliphora vicina, which occurs throughout the year and was present in 69 % of all cases. Lucilia sericata, Calliphora vomitoria, and L. caesar were identified among the rest of the flies as species of great forensic importance mainly due to their distributional patterns. After a comparison with a similar dataset from Frankfurt, Germany, some surprising differences were determined and discussed. The biggest discrepancies between our dataset and the German dataset were in the occurrences of L. sericata (30 % vs. 86 %, respectively), Phormia regina (5 % vs. 43 %), and L. ampullacea (1 % vs. 45 %). The life-history strategies and intraspecific behavioral variability of blowflies remain understudied, although they can be essential for an unbiased approach during a death investigation. Further research and comparison of occurrence patterns across the area of distribution of blowflies are therefore needed and recommended.

Parasite and pathogen surveillance is crucial for understanding trends in their distributions and host spectra, as well as to document changes in their population dynamics. Nevertheless, continuous surveillance is time-consuming, underfunded due to the non-charismatic nature of parasites/pathogens, and research infrastructure is usually limited to short-term surveillance efforts. Species observation data provided by the public can contribute to long-term surveillance of parasites using photographic evidence of infections shared on community science platforms. Here, we used public photo repositories to document the occurrence across space and time of Lucilia spp. (Diptera: Calliphoridae), a parasite inducing nasal toad myiasis in the European toad Bufo bufo (Anura: Bufonidae). We found a total of 262 toad myiasis observations on iNaturalist (n = 132), on GBIF (n = 86), on Flickr (n = 41), and on observation.org (n = 3). Our results indicate that the distribution of toad myiasis is regionally limited, despite its host being widely distributed and abundant across a wide region in Europe. Observations were found in 12 countries with relatively low prevalence, including Belgium (3.90%, CI 2.44–6.18), Denmark (1.26%, CI 0.89–1.80), France (0.45%, CI 0.14–1.38), Germany (1.27%, CI 0.92–1.75), Lithuania (0.50%, CI 0.13–1.98), Luxembourg (1.30%, CI 0.42–3.95), the Netherlands (2.71%, CI 1.61–4.52), Poland (0.89%, CI 0.34–2.35), Russia (Kaliningrad Oblast) (4.76%, CI 0.67–27.14), Switzerland (NA), Ukraine (0.87%, CI 0.12–5.91), and in the UK (0.45%, CI 0.28–0.72). Nevertheless, the number of uploaded observations of both parasite infection and host presence indicates a stable increase likely due to the growing popularity of community science websites. Overall, community science is a useful tool to detect and monitor certain wildlife diseases and to recognize potential changes in disease dynamics through time and space.
