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.

Ornate Soldier Fly

A medium-sized soldier fly with a green and black patterned abdomen and a somewhat flattened body. Adults are sluggish fliers often found basking on waterside vegetation.

💡
