I can attest to lawns being the enemy. For many years I grew a dense native plant yard and literally have tens of thousands of pictures of terrestrial arthropods ok a lot of dupes of individuals but also amazing biodiversity and multispecies and social phenomena like ant symbiosis which I wrote about here: http://www.elegantcoding.com/2016/05/my-ant-symbiosis-storie... and opiliones social behavior. It was amazing. They only problem is that it is illegal and I was forced to destroy all of my native plants by my local municipality. As a result the insects disappeared.
