Golden Reed Beetle
A slender, metallic beetle with golden to coppery-green coloration and elongated antennae. It is commonly found resting on emergent aquatic vegetation in ponds and marshes.
Did You Know?
Adults possess hydrophobic hairs on their underside that trap a thin film of air, allowing them to survive brief submersion.
Black Headed Birch Sawfly
A medium-sized sawfly with a dark head and orange body. Larvae are greenish-blue with black heads and feed communally on birch and alder leaves.
