not unless you had SIGNIFICANT drought ... thereby baking the grass above tunnels ... then the question would be.. did you water ...

can you collapse any tunnels with your foot??? ... have you tried digging out a patch.. to see if there is a tunnel????

you might want to try the lawn forum also.. should we fail ...

Lol, the pattern is very interesting...I've never known a mole to dig such elaborate tunnels.

Lol.....I'm laughing WITH you, not at you! I promise you that your lawn has not been invaded by skillful and artistic moles. That's a perfectly normal phenomenon seen in bermudagrass after the first hard frost. It doesn't happen every year, the environmental conditions have to be right.

What happens is that the soil absorbs heat from the sun during the day and is radiated back up at night. That radiated heat is enough to prevent frost damage, but because of the pattern and growth habit of the turf, some blades get zapped while others stay green.....until the next time. It's normal thermodynamics and very common.

That's not to say that you don't have moles....you might! But you'll know a mole tunnel when you see it. Even mole crickets don't cause that kind of patterning.

Don't worry, your lawn will soon be the same color.

Thank you all. Now I will just enjoy the lovely pattern.
