What makes a water strider a true bug?
True water striders are distinguished from other skating bugs by their long middle and hind legs. They may communicate by rippling the water surface. Adults may or may not have wings. Water Quality Indicator: Because water striders don’t actually live in the water, they are not very useful indicators of water quality.
What negative environmental impacts could be associated with farming bugs?
In addition, current livestock production contributes greatly to a number of environmental problems such as acidification due to leaching of ammonia, climate change due to greenhouse gas emissions, deforestation, soil erosion, desertification, loss of plant biodiversity, and water pollution.
What wildlife does a small pond attract?
Ponds make a lovely addition to any garden and they’re also a proven way of attracting wildlife. Often, even small ponds attract a wide range of visitors, from the obvious frogs and newts to the perhaps more unexpected hedgehogs and birds.

They are reliable indicators because they spend all or most of their lives in water, are easy to collect and differ in their tolerance to pollution.
Why are there water skippers in my pool?
