Some seasonally active carrion invertebrates leave remnants of their presence that remain long after the completion of flesh decay. Remnants may include fly puparia (pupal cases) or insect exoskeletal elements. The presence of these remnants among old, decomposed remains can therefore indicate possible months in which death occurred. A large-scale study of the patterns of neonatal piglet decomposition and carrion insect succession in a forest was carried out in 1999 and 2000. Five fresh piglet carcasses were exposed once per season in both years and visited frequently throughout decay. Ten seasonally active taxa, likely to leave durable remnants of their presence were selected, and profiles were constructed of their activity times over the 2-year study.
