In natural forests, fire is an important disturbance factor and many studies have been carried out concerning its effect on different ecosystems, but no studies have previously been done considering the scuttle flies in hemiboreal forests. Here, we carried out an ecological investigation of the scuttle fly assemblage in a hemiboreal old-growth forest in Tyresta National Park and Nature Reserve (Sweden) from material collected, using Malaise traps, after wildfires in 1997 and 1999. We evaluated abundances of species, dominance structure, species richness (by non-parametric species richness method — Chao 1) as well as phenology. The most abundant species of the dominant group (i.e. Megaselia pleuralis, M. nigriceps, M pulicaria-complex and M. brevicostalis) are multivoltine and saprophagous, displaying spring and late summer/autumn activity.
