The blowflies Calliphora vicina and Calliphora vomitoria are among the first colonizers of human remains in Europe. Laboratory development studies with immature stages of these blowflies for postmortem interval (PMI) calculations are generally performed on different media such as processed food substrates or liver of various animals. The question arises… (More)
Development of larvae of different forensically important flies under constant low, medium and high temperatures as well as under daily fluctuating temperatures in a climatic chamber was investigated and compared. Results suggest faster development under fluctuating temperatures for Sarcophaga argyrostoma and Lucilia illustris but slower development for… (More)
The muscular attachment sites (MAS) of blowfly larvae can be visualised as “dots” by removing and staining the cuticle. Each segment bears several rows of MAS. The silhouettes of a subset of those rows in the second, third, and fourth segments were previously shown to be specific for four species of L3 blowfly larvae. In this investigation, the MAS patterns… (More)
Decomposition processes and insect succession were analysed on a total of eight pig (Sus scrofa) carcasses. The survey was carried out in four different periods between November 2007 and August 2008 and on two different substrates (meadow, concrete floor close to a building). The experiments were placed in a rural site in the surroundings of Jena,… (More)
First results of a new method for species determination in third instar larvae of saprophagous blowflies are introduced. Cuticular attachment sites of a limited number of transversal muscles are visualized for light microscopic analysis. After removing the muscles and staining the cuticle, the attachment sites become visible as laterally symmetrical… (More)
A simple clearing technique is presented by which species specific structures and organs of blowfly larvae can easily be visualized and displayed without any danger of mechanical damages or dislocations of delicate formations and without fixation of the object.
Species identification is generally assessed to be more difficult in larval stages than in adult forms. Especially closely related species such as Lucilia caesar and Lucilia illustris are difficult to identify. The aim of this study was to simplify species determination in Lucilia larvae for entomological and forensic purposes. Muscle attachment site (MAS)… (More)
An error was found in a previous publication on muscle attachment sites in forensically important blowfly larvae from 2012. The patterns we assigned to Lucilia illustris factually belong to Phormia regina.
Like in all poikilothermic animals, higher temperatures increase developmental rate and activity in Calliphora vicina larvae. We therefore could expect temperature to have a persistent effect on the output of the feeding and crawling central pattern generators (CPGs). When confronted with a steep temperature gradient, larvae show evasive behavior after… (More)
Estimating time of death of buried human bodies is a very difficult task. Casper's rule from 1860 is still widely used which illustrates the lack of suitable methods. In this case study excavations in an arbor revealed the crouching body of a human being, dressed only in boxer shorts and socks. Witnesses were not able to generate a concise answer as to when… (More)
