Come Autumn it is common practice to have the fallen leaves on your property raked up and removed. It can also be hard to resist with so many landscaping companies offering to do it for cheap.
One of the many reasons to leave them where you can is that they create ideal firefly habitat. The females lay their eggs in moist areas, usually near ponds or streams. However, in areas where that's not an option they will lay their eggs underneath leaf litter where they are insulated and moisture is retained.
So if you have parts of your property where leaves really don't need to be removed, let them be. After all, who doesn't enjoy the radiant presence of fireflies?
