What is wrong next to my Lawn (PICS)? Most of my lawn is green but this particular nouns on it...

Most of my lawn is green but this particular nouns on it has these brown/patching areas (notice the moss thingy in one of the pix and how my biggest lawn is green except for that area) ... take a look at these pictures and bestow me your analysis:

Some fact:
- Lawn is watered
- Lawn is fertilized

Could there be an insect problem underneath?

Is the grass surrounded by those browning areas dead because its been raining (and ive be watering) and it remains brown :(
powerfully that is a problem. Your first pic show's what looks like grass mold which is remedied by a fungicide. I can't report about the other spots but if there is mold present within all the areas its a safe bet i.e. your problem. You can buy the fungicide at most home centers. here's a helpful website...

check out the 'frog eye'.

as far as treatment, I know Bayer is used by the landscape squad at the retirement village near us... took their tour and saw it contained by the sheds!!. they have great grass!!...

beyond what you see here, take those pics to your Master Gardeners at the County extension department. they'll have someone really knowledgeable more or less lawn care to sustain you further.
I have had a look at your extesive presentation of pictures. The patch are not "a complete circle, rather horse-shoe shaped, so I have eliminate a similar indication of infection whose name escapes me, which has complete circles of brown unresponsive grass. No, I can only guess that this could be the larvae of the "Crane Fly", namely the leather jacket. From impulsive Summer onwards they will be busy chewing on the roots, any soft roots in this case your grass roots. Now if this is the overnight case the way to get rid of them lacking chemicals is to spread a black plastic cover over the patch, make sure you anchor it, and in the morning remove it, Preferably as impulsive as possible after dawn, You will find that they all hold come to the surface, and will be breakfast for spiders, starlings and other natural predators. I would say this would be a all right worthwhile experiment. Happy gardening You may have two problems.
Fisrt is brown patch - treat with a fungicide and insure you are not watering after sunset - don't put your grass to bed raining.

Second may be grubs or other insects - Dig in the area and see if nearby are any grubs - for surface insects, take a coffee can and cutr out the bottom. Push the can into the ground about an inch. Pour contained by a solution of Lemon Joy soap (1 tablespoon) to a gallon of water (You can use other dish soaps, lemon joy works best). Let it sit for a few second. If there are any surface insects they will come to the surface.
Treat with an insecticide.

But my guess from the pics is Brown Patch fungus.
Dead grass, you need the help of a landscape company pronto! throw some weed -n- feed on it. if that doesnt work then try a coctail of fungasides and insectides
We had that same problam the dogs was releveing hemself contained by some of the spots. And then agean it could the ground is to hard and the pip, fertilizer are any thing is able to tack hold. (befor the birds draw from it.) Try loseing the ground just a little and kernel & fertilizing it.

Good Luck.
Answers:    yea its grubs
treat the whole lawn when you do not only the spots
Do you or your neighbors enjoy a dog? I'm thinking they might be relieving himself on your grass
