These weird and wonderful critters are a useful way to tell
how healthy a waterway is, because:
- Some water bugs don’t mind living in polluted water,
but others die from it or will move elsewhere.
- They are important members of the living world. About
99 out of every 100 animals are invertebrates (have no spine
or backbone).
- Water bugs help many other animals and plants to live.
They are important members of the freshwater community and
perform a number of roles in the food web.
It's easy to help find out the health of our waterways because
water bugs are found everywhere there's water. And they're
fun to catch!
