Crawling Water Beetle
A tiny, oval water beetle with a yellowish body covered in rows of dark punctures. Unlike diving beetles, it crawls slowly among aquatic vegetation rather than swimming actively.
Did You Know?
It stores air beneath enlarged hind coxal plates, which act as a built-in oxygen reservoir while submerged.
Giant Case-Builder Caddis
A large caddisfly with spotted wings found in northern and central Europe. Larvae construct conspicuous helical cases from plant material in weedy waters.
Did You Know?
Its larvae are among the few caddisflies known to actively prey on other aquatic invertebrates.
