I have participated in No Mow May for three years now. I also have a spot in the yard I let be free (weeded it for invasives) for the same amount of time.

This summer, for the first time since I have lived here, exsists an abundance of fireflys in my yard. They are everywhere, in a way I've never seen since I was a child.

No Mow May, (even if just a part of your yard) gives insects a place. Bugs live in the leaves and natural debris, by keeping it undisturbed, from fall to winter is important for many bugs' survival.

If you like bugs, consider dedicating space in your yard for them to live. Don't keep grass in the typical american perfect lawn way. I suggest not to spray, and look at native grasses and plants first when seeking your landscaping needs.

I've noticed a real difference this year in my yard. Maybe its some coincidence, I don't know. Either way I'm happy to see lightning bugs again
