Brown-winged Rove Beetle
A large, uniformly dark rove beetle with subtly brownish elytra, closely related to Tasgius melanarius. It prefers more rural habitats than its congener and is often found in agricultural landscapes.
Did You Know?
Farmers historically considered this beetle beneficial, as it actively hunts crop-damaging leatherjackets in agricultural soils.
Beautiful Demoiselle
A stunning damselfly with entirely dark-tinted wings in males and bronze-green wings in females. It prefers faster-flowing, well-oxygenated streams.
Did You Know?
Beautiful demoiselles are indicators of clean water quality, as their larvae can only survive in well-oxygenated, unpolluted streams.
