The identification of necrophagous insect diversity and dynamics has forensic significance for postmortem interval estimation specific to burial. Few studies regarding the necrophagous entomofauna from buried remains have been performed to date. In contrast to the exposed carcasses, the accessibility of soil to insects is limited due to burial depth and is dependent on soil type. This study highlights the colonization behavior of Conicera similis (Haliday 1833) (Diptera: Phoridae) during carcass decomposition, a previously unobserved taxon in Romania. Adult and larvae specimens were collected from rat (Rattus norvegicus) carcasses buried at 40 cm depth in an urban park environment in June 2016 during active decomposition and their presence and activity period was correlated with the environmental parameters variation. Bacterial diversity from C. similis female adult and larvae specimens was determined via 16S rRNA gene Illumina sequencing to further characterize these commonly encountered and forensically important necrophagous insects. This report signals the easternmost geographical location in Europe (Bucharest, Romania) of C. similis to date.
