Full-text available
Carrion consumption by scavengers is a key component of both terrestrial and aquatic food webs. However, there are few direct comparisons of the structure and functioning of scavenging communities in different ecosystems. Here, we monitored the consumption of 23 fish (seabream Sparus aurata) and 34 bird (yellow-legged gull Larus michahellis) carcas...

The Locard′s exchange principle (1930) holds that the perpetrator of a crime leaves traces behind that can later be sampled and used as forensic evidence [...]
Article
Full-text available
Piophilidae are a relatively small family of Diptera that is frequently associated with cadavers at advanced stages of decomposition and are, therefore, considered potentially useful forensic indicators. However, their use in forensic investigations is typically hampered by a deficiency in reliable identification tools. This is particularly evident...
Article
Unlike most larval organs and tissues, the central nervous system of holometabolous insects persists into the adult stage, although profoundly remodelled and with some neuropils largely newly formed during metamorphosis. Among the neuropils, those forming the optic lobes are particularly relevant as they are the visual processing centres and compri...

Full-text available
Scavenging is key to understanding ecosystem structure and functioning, both in terrestrial and aquatic environments. Here, we compare the structure and carrion consumption efficiency of the scavenger communities occurring in terrestrial and shallow marine habitats on and around a Mediterranean island. During July 2018, we monitored the consumption...

Onchocerciasis is a neglected tropical disease (NTD) caused by Onchocerca Diesing 1841 (Spirurida: Onchocercidae) nematodes transmitted by blackflies. It is associated with poverty and imposes a significant health, welfare and economic burden on many tropical countries. Current methods to visualize infections within the vectors rely on invasive met...
Article
Cava Muracci (Cisterna di Latina, central Italy) is a complex of seven karst caves located in the Pontine Plain region. One of them, denominate Area 3, displayed a well-preserved Late Pleistocene deposit dating from 35 ka BP and older containing abundant mammal remains and cave hyena coprolites. This work presents the recent discovery from this dep...
Article
Oestrid flies (Diptera: Oestridae) do not feed during the adult stage, so they depend on an efficient assimilation and storage of nutrients during their parasitic larval stage. We describe the general morphology and provide volumetric data for the digestive and excretory organs of the three larval instars of the nasal bot fly Oestrus ovis L., using...
Article
During the larval stage, oestrid flies (Diptera: Oestridae) are obligate parasites, whereas during the adult stage they are free‐living and do not feed. Like other cyclorrhaphous flies, oestrids undergo metamorphosis inside an opaque puparium, formed by the contracted and hardened cuticle of the third‐instar larva. The present study documents the i...
Article
The Piophilidae (Diptera) are a family comprising about 80 species, several of them of high economic and forensic relevance. An unequivocal species identification is crucial for designing effective control measures or to provide reliable estimations of the minimum post mortem interval. However, the identification may sometimes not be possible, eith...
Article
Metamorphosis and, in particular, holometaboly, the development of organisms through a series of discrete stages (egg, larva, pupa, adult) that hardly resemble one another but are finely adapted to specific roles in the life cycle of the organism, has fascinated and mystified humans throughout history. However, it can be difficult to visualize the...
Article
The importance of temperature data in minimum postmortem interval (minPMI) estimations in criminal investigations is well known. To maximise the accuracy of minPMI estimations, it is imperative to investigate the different components involved in temperature modelling, such as the duration of temperature data logger placement at the crime scene and...
Article
Full-text available
Baseline data on the insect successional patterns on carcasses can be a valuable estimation tool in the investigations of suspicious deaths, particularly when the post-mortem interval is longer than months or years. However, although carrion insect succession is a recurrent topic in forensic science research, the duration of the published studies i...
Article
Full-text available
Carrion resources sustain a complex and diverse community of both vertebrate and invertebrate scavengers, either obligate or facultative. However, although carrion ecology has received increasing scientific attention in recent years, our understanding of carrion partitioning in natural conditions is severely limited as most studies are restricted e...

Full-text available
The Piophilidae (Diptera) are a relatively small family comprising around 80 species of mainly sarcosaprophagous habits. Piophilids can represent major pests for the food industry, but can also be used as forensic indicators in forensic investigations. In this kind of investigations, a reliable identification of the collected material is an essenti...
Article
Full-text available
Several necrophagous Coleoptera species are frequently collected on cadavers, may occasionally act as intermediate or paratenic hosts of parasites, as vectors of pathogens or as allergens, and can also represent major pests of preserved animal products. However, despite their medical, veterinary and economic importance, there is a lack of reliable...
Article
Taphonomic modifications to Neolithic human skeletal remains from six rock-cut tombs in Malta has provided key information about funerary practices and the local environment. Application of microscopic analysis, computed tomography (CT) scanning, and 3D imaging of the modifications has allowed their comparison with similar examples in modern and ar...
Article
Full-text available
Some parasites are able to manipulate the behaviour of their hosts to their own advantage. One of the most well-established textbook examples of host manipulation is that of the trematode Dicrocoelium dendriticum on ants, its second intermediate host. Infected ants harbour encysted metacercariae in the gaster and a non-encysted metacercaria in the...
Article
Full-text available
The variation in decomposition and insect succession among the four seasons of one year was studied for the first time in a periurban area of central Spain. During the winter trial, the carcasses showed corification, a cadaveric preservation phenomenon which apparently leaded to a significant delay in decomposition processes. The composition of the...
Article
Oestrid flies (Diptera: Oestridae) do not feed during the adult stage as they acquire all necessary nutrients during the parasitic larval stage. The adult mouthparts and digestive tract are therefore frequently vestigial; however, morphological data on the alimentary canal in adult oestrid flies are scarce and a proper visualization of this organ s...
Article
Full-text available
Minimum post-mortem interval (minPMI) estimates often rely on the use of developmental data from blow flies (Diptera: Calliphoridae), which are generally the first colonisers of cadavers and, therefore, exemplar forensic indicators. Developmental data of the intra-puparial period are of particular importance, as it can account for more than half of...
Article
Due to their ubiquity and synanthropy, blow flies (Diptera: Calliphoridae) are generally the first colonisers of cadavers and, therefore, frequently used to estimate a minimum post-mortem interval (minPMI). Whereas in outdoor situations blow flies are expected to locate and colonise exposed cadavers within hours or even minutes after death, it is u...
Article
Most Dermestes species (Coleoptera: Dermestidae) are scavengers during both larval and adult stages, with a preference for dry organic matter. Because of this, Dermestes beetles are potentially useful indicators in forensic investigations concerning skeletonized and mummified human remains. However, there is a paucity of reference developmental dat...
Article
The genus Prochyliza Walker is recorded for the first time from the Afrotropical Region. A new species, Prochyliza ignifera sp. nov., is described from the Indian Ocean islands of Aldabra and La Réunion. The status of this species as possibly the most primitive in the genus Prochyliza is hypothesised and discussed, raising some questions about the...
Article
Full-text available
Metamorphosis of cyclorrhaphous flies takes place inside a barrel-like puparium, formed by the shrinking, hardening and darkening of the third-instar larval cuticle. The opacity of this structure hampers the visualization of the morphological changes occurring inside and therefore a full understanding of the metamorphosis process. Here, we use micr...
Article
Full-text available
The dramatic metamorphosis from larva to adult of insect orders such as Diptera cannot usually be witnessed because it occurs within an opaque structure. For the cyclorrhaphous dipterans, such as blow flies, this structure is the puparium, formed from the larval cuticle. Here, we reveal metamorphosis within the puparium of a blow fly at higher temp...
Article
Piophila megastigmata McAlpine (Diptera: Piophilidae) is recorded for the first time from Algeria, northern Africa. This is the first Palaearctic record of the species outside the Iberian Peninsula, and the only record from Africa apart from its type locality in eastern South Africa. The current report extends significantly the known distribution i...
Article
The value of minimum post-mortem interval (minPMI) estimations in suspicious death investigations from insect evidence using temperature modelling is indisputable. In order to investigate the reliability of the collected temperature data used for modelling minPMI, it is necessary to study the effects of data logger location on the accuracy and prec...
Article
Developmental studies of necrophagous insects are strongly needed to support medico-legal investigations, because minimum postmortem intervals (minPMI) can be estimated from development data for species collected from a forensic scene together with accurate temperature information from that scene. The life cycle of cyclorrhaphous flies, which inclu...
Article
Full-text available
Blow fly eggs may sometimes be the only entomological evidence recovered in a forensic case, especially in cooler weather when hatching might take several days: hence, a method for estimating their age is greatly needed. However, developmental data on blow fly eggs are mainly limited to records of the time to larval hatching. The current paper desc...
Article
Species identification plays an important role in forensic entomology and is mandatory for an accurate calculation of the minimum post-mortem interval. Many important Diptera and Coleoptera taxa of the cadaver community can already be identified by common barcoding approaches, i.e., by sequencing a 658 bp region in the mitochondrial cytochrome c ox...

Considered at times as extinct, the European bone-skippers Thyreophora cynophila and Centrophlebomyia furcata (Diptera: Piophilidae) have been recently rediscovered in Spain, coexisting in some areas. Nevertheless, apart from their typical association with big mammal carcasses, little is known about them and the other species of subtribe Thyreophor...
Article
The composition and spatial distribution of sarcosaprophagous Diptera assemblages were studied using carrion-baited traps along a bioclimatic gradient of natural habitats in central Spain throughout the different seasons during 1 year. Calliphoridae and Muscidae were the most abundant families, accounting for, respectively, 41.9% and 35.1% of all D...
Article
Full-text available
Although crickets, katydids and grasshoppers (order Orthoptera) are generally considered archetypical examples of herbivory, cumulative evidence shows that they are actually omnivorous, feeding on a wide range of organic matter, including carrion. The present study compiles the collections of 30 Orthoptera species, from both suborders, Ensifera and...
Article
Full-text available
Abstract The use of carrion-baited traps is a common and widely extended practice in the study of sarcosaprophagous Diptera. However, it implies different areas of bias, one of them being the different responses of males and females to carrion bait, which results in possible biased sex ratios in the captures. In the present study, the use of carrio...
Article
Full-text available
Flies of family Piophilidae have been recorded as major pests in the food industry, as agents of human myiasis and typically associated with carcasses in advanced stages of decay, being thus important in forensic entomology. Despite that the cosmopolitan species Piophila casei is the most cited in entomological studies, many other piophilid species...
Article
Full-text available
The composition, spatial distribution, and seasonal fluctuations of necrophagous Coleoptera assemblages of families Dermestidae and Silphidae are studied along a bioclimatical level gradient of natural habitats in central Spain. Both families were collected with carrion-baited traps throughout a year. The main part of the individuals occurred in sp...

The European bone-skippers Thyreophora cynophila and Centrophlebomyia furcata (Diptera: Piophilidae) had been considered as globally extinct or extinct in Europe, respectively, until their recent rediscovery in Spain. Improved hygienic conditions in livestock management and disposal of large carcasses (the preferred breeding sites for the bone-skip...
Article
Among the insects which are typically considered of forensic interest, the family Piophilidae (Diptera) is frequently cited because of its common occurrence on carcasses in different stages of decay. Piophilids are mainly known from the cosmopolitan species Piophila casei, which can be also a major pest for the food industry and an agent of myiasis...

Full-text available
The occurrence of colour polymorphism in wild populations of the necrophagous fly Prochyliza nigrimana (Diptera: Piophilidae) is recorded but never treated in detail. The present paper shows that there is a seasonal distribution in the morphotypes, with the dark morphs emerging in spring and pale morphs emerging later and most abundant in summer. F...
Article
The genus Piophila Fallén (Diptera: Piophilidae) is known from only two species: Piophila casei (L.) is a major pest, a cosmopolitan species and is commonly used as a forensic indicator, whereas Piophila megastigmata McAlpine has until now only been recorded in a natural environment in South Africa. The present work reports the first occurrence of...
Article
We report on a sensational find in central Spain of six specimens of Thyreophora cynophila (Panzer, 1798), a colourful, strange-looking piophilid fly living on carcasses of big mammals in advanced stages of decay. Published data suggest that the species is known exclusively from central western Europe (Germany, Austria and France), and was observed...
