The Compound Eye of Calliphora Vomitoria (Bluebottle fly)

Business Engagement, HEIF, Info Days, international, Knowledge Exchange

“Blood feeding activity of flies at crime scenes can be confounding. Experiments were conducted to investigate the blood feeding activity, and blood artefact patterns created by flies following a blood meal. The trials were undertaken in a staged environment where over 500 flies were exposed to 500ml of horse blood in a sealed gazebo for a period of 72 hours. The resulting patterns, a total of 539,507 fly blood artefacts, were then compared to recreated bloodstain patterns commonly encountered during instances of violent assault. These comparisons focused on overall pattern shape, total stain numbers, stain density per cm2 and the zone where they were deposited. Informal observations and recordings were also made of individual stain colour and stain alignment, but were not measured.”

This was the abstract submitted to accompany Christopher’s recent submission to the Research Photography Competition, where he won second prize.

Christopher Dwen  is currently working as a Research Assistant on an innovation funded (HEIF) project called: “Sherlock’s Window”. This  HEIF-funded project at BU  aims to produce an odourless growth medium that can be rolled out internationally for use in forensic investigation. Find out more about the project in the latest edition of the Bournemouth Research Chronicle featured in the section:  “Innovation in industry:how researchers and the wider community are working together.” –
