Is it the grass that is dying, or is it heaps of soil from ants' nests?
By the way, it won't be dragonfly larvae as they lay their eggs in ponds. I expect your neighbour means cranefly larvae (known as leatherjackets) - they eat the roots of plants -
http://simple.wikipedia.org/wiki/Crane_fly
When you see starlings and crows probing into the turf on meadows and playing fields etc it's the cranefly larvae that they are looking for. It may be that this is a bad year for leatherjacket infestations as they like the ground to remain damp throughout the summer.
If it is leatherjackets it will be the grass itself that is yellowing and dying (not heaps of soil). If you have a bad infestation you can treat with nematodes vhttp://www.harrodhorticultural.com/nemasys-leatherjacket-killer-pid7625.html and it's cominng up to the right time of year to do it.
If it is ants making ant hills, then there are also nematodes to deal with them http://www.unwins.co.uk/nemasys-no-ants-pid2590.html
We've got red ants in our lawn, but as we've got green woodpeckers in the area I'm hoping that the ants will attract them to our garden and they will deal with them for us.

@dovefromabove... there is not really any humps of soil.. only a few.. but it it the grass.. just dying and dried out and dead..can just scrap it off.. so youmay be right.. so it is cranefly larvae.. the magpies do go around sticking their beaks on..
so i will check out links you gave me.. thank you.. i cant bear to look at it at mo.. was looking so gorgeous at beginning of year.. now it is dreadful.
hubby happy as now he can breath sigh of relief.,.he thought he might of done it when cutting the grass.
Before your Hub gets too relaxed about things there are a few things he can do to help
Ask him to get a lawn rake and give the lawn a good raking to remove any dead grass and thatch, and then spike the lawn all over with a fork to improve the drainage, and when he mows the lawn ask him not to mow it too short as 'scalping' the grass won't help. Then a dose of summer lawn feed or even some 'seed & feed' should improve things.

@dovefrom above.. hubby dont do that.. green thumb do.. they gave it feed and what not last month.. said nothing about brown patches.. they scraified and airated it etc in march so wont do again till october.. i have rung them and got them coming to have a look at it..
Now I'm worrying - there's just a possibility that it mght be fusarium which can be spread from one lawn to another on equipment - does it look anything like this?

Just one suggestion-is there a dog that visits the garden?-or perhaps a fox?
@dovefromabove. no nothing like those.. it had red thread last year andhtey treated after we had snow.. or was that year before no white stuff or redness to it.. just yellow then dying..
@geoff.. not dogs no.. but we get foxes round here and badgers too..
I think a picture is going to help answer this-it is just stabbing in the dark at the moment
So can you post a picture please?
of geoff.. will take one tomorrow.. as too dark now.. that is if not raining to much.. thanks for replies.. much appreciated.
ok here are some piccies taken this morning...
i cant see an y red thread or white mouldon it anywhere.. just looks like it is dying.. here it was on the 9th aug just starting to show signs...
and now..
