Sažetak
Brachinus crepitans Linnaeus 1758 is a species of dry, open habitats. Previous studies have shown that in Croatia, this species inhabits open habitats, but is not restricted to dry habitats. The objective of this study was to investigate the distribution and seasonal dynamics of B crepitans at four sites with varying vegetation types around a small, shallow aquatic area. Pitfall traps and the capture-recapture methods were used. The results show that B crepitans prefers open, periodically fl ooded habitats, though it was also found in dense, closed complexes with Amorpha fruticosa. Seasonal dynamics varied from those observed in Central Europe. Population density was estimated at 1.42 beetles m-2.
