Calliphora vicina larvae grow at different rates on different body tissues

Compared with the rate on pig's liver, larval growth of the blowfly, Calliphora vicina is significantly faster by as much as 2 days on lung, kidney, heart or brain tissue. Potentially this has major implications when laboratory growth rates of larvae fed on one food substrate (often liver) are used to calculate the amount of development, and therefore the postmortem interval in a forensic case.
