Tips of Grass turning Brown

Hello,
Any advise on why the top half of some of my grass is turning Brown?
Only effected one area at the moment, but is quite large.
Lawn is South facing, so in sun all day, but the browning hasn't effected other areas of grass in full sun yet?
I last mowed it 6 days ago on the highest setting, and whole lawn was lovely and Green.
Grass only started to go Brown since 3 days ago.
Still Green at the bottom, but going Brown and dying at the top.

Would bugs be the culprit?
I have noticed small, White slug-type bugs in the lawn in the evenings (almost maggot sized).
Could they have anything to do with it?

Any assistance appreciated.
Thanks,

    Any number of possible causes. Could be heat and dryness (mine has areas that always brown first, maybe the soil is poorer in those patches). Could be from cutting with a mower blade that isn't sharp enough or has a damaged area so it tears the blades of grass instead of slicing cleanly. Or maybe something's been spilled on there. There look to be "trails" or rings of browning, but that could be due to damage on one end of the mower blade if you use a rotary type.

    I agree with @JennyJ
    … my first thought was that looks as if it’s been chewed and torn by a blunt or damaged mower blade.

    Ok.  Thanks for your replies.
    Ill check the mower blade out, but if this was the case, then Id expect the whole lawn to be the same, but its not?
    Ill give it another high cut and spike tomorrow as rain is expected at weekend, so hopefully the Greener grass will grow through?
    Thanks again.

    Unlike the majority of plants, grass leaves grow from the base rather than the tip, so as long as there is green at the base, all is good.  That's the main reason we use grasses for mown or grazed areas. :)
    A trowel in the hand is worth a thousand lost under a bush.

    I wonder if maybe you dinged the blade on a stone or something partway through the last cut? Also if your lawn is older, there could be patches of different types of grass in it (I know mine has) and some are tougher to cut through and more likely to look ragged than others.
