Coastal Rove Beetle
A medium-sized rove beetle with yellowish elytral margins, highly adapted to life on seashores. It lives under seaweed wrack on beaches where it preys on kelp fly larvae.
Did You Know?
This beetle can survive temporary submersion in seawater during high tides by trapping an air bubble under its elytra.
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.
