I stopped mowing my lawn after I realized earlier in the season that it had an impact on my skipper population. At first I expected hip-high overgrown weeds, but instead the grass stopped growing and laid down flat, and it's actually easy to walk on. Clover has sprouted up everywhere. The bees and skippers love it. Also, I hear crickets now every time I go outside, and I used to rarely hear crickets in my suburban yard.
I am also planning to mulch less, and throw out fewer plant trimmings, since I realized I was probably throwing away butterfly eggs, larvae, and cocoons by over-mulching and over-cleaning. Now I am more careful.
