Forensic entomologist unearths Chinese migrant fly in Europe

Forensic entomologists - who gain vital crime scene information such as time of death by studying the infestation of human cadavers - need to learn as much as they can about the newcomer. The University of Huddersfield's Dr Stefano Vanin, assisted by some of his students, is leading the way.
