Re: Maybe if they collected less insects, there would be more around...
Personally I don't understand the whole desire for a grass lawn having grown up mowing the better part of two acres most weekends as a kid. I much prefer the low maintenance of things like clover, creeping thyme, low growing sedums, hazelwort, moneywort, creeping buttercup, hen and chicks, etc. All are relative low growing so keeping spaces open to highlight taller varieties. Sure it takes care in the beginning to select plants appropriate to the environment and getting them established but the ability to finally lose the lawnmower is bliss. Of course it requires also being fee from the tyranny of a homeowners association or a city which mandates a crisp green lawn.
