Icelandic Water Beetle
A medium-sized, oval, dark brown diving beetle found in cold ponds and lakes. It carries a silvery air bubble under its elytra for breathing underwater. Adults are strong fliers and can colonize isolated Arctic ponds.
Did You Know?
This beetle is one of the most widespread diving beetles in the Arctic and can fly long distances to colonize new ponds created by permafrost thaw.
Rainbow Ground Beetle
A spectacularly colored ground beetle with elytra showing bands of metallic green, copper, and red, with three prominent raised ridges. It is associated with wet heathland habitats.
Did You Know?
Its brilliant rainbow coloring makes it one of the most beautiful European beetles, yet it is increasingly rare due to the drainage and destruction of its specialized heathland habitat.
