In Europe, the blowfly genus Lucilia is represented in Forensic Entomology mainly by the species L.
ampullacea, L. caesar, L. illustris and L. sericata. In the US, Lucilia silvarum is rarely recorded as a carrion
breeding species but usually as a more or less exclusive parasite of frogs and toads. We present three
forensic cases from different European countries reporting, for the first time, L. silvarum on human bodies
that were found close to lakes, wetlands, or riversides. To use this species for post-mortem interval
estimations, thermal development data is needed. The first step is accurate identification by
morphological and molecular means. Therefore, we analysed a 611 bp part of the mitochondrial COI
region for 23 specimens of L. silvarum from 9 different geographical regions, all of which give the same
haplotype. Differences within the haplotype varied by up to 0.2%. Comparison between the haplotype
found and those published on GenBank showed up to 1.2% variance. Moreover, we present an updated
key for the morphological identification of the third larval instars of European Lucilia spp. of forensic
importance, adding not only L. silvarum, but also L. cuprina which was recorded in Europe for the first time
about 20 years ago.
