Abstract

Introduction: Synthesiomyia nudiseta (Wulp) (Diptera: Muscidae) is a forensically important fly in many countries, and is normally associated with corpses found indoors. Objective: In this paper, the presence of an adhesive substance produced during prepupal development was reported and described. Methods: Numerous prepupae and puparia of this species were found adhered side-by-side on a mattress, where a decomposed body was discovered inside an apartment in Kuala Lumpur, Malaysia. Results: The immature stage, in particular the pupa, displays a special characteristic which may assist early species identification for forensic investigation. The surface ultrastructure of the adhesive layer analysed by scanning electron microscopy showed a sponge-like appearance. Conclusion: We suggest this adhesive substance may be secreted by this species as a protective mechanism to prevent it from being predated by other insectivorous predators. Based on the specimens analysed, the post-mortem interval for this case was estimated to be between 9 to 13 days.
