RESUMO
Six freshly killed rabbit carcasses were exposed in different habitats in the coastal dune massif of Ambleteuse (northern France) during the spring seasons of 1996 and 1997. In total, 66 arthropod species were collected during the decomposition of these carcasses, and particular attention was paid to taxa of necrophilic significance. The pattern of insect activity was recorded and is discussed in relation to meteorological conditions. One significant feature in this study was the delay in initial oviposition by flies during 1996, which demonstrates the need for caution in estimation of postmortem interval by entomological techniques in early spring. Although daily temperatures may be favorable for adult fly activity, flies may be absent because of small population size and low nocturnal temperatures during this period.
