[4th season allot]

Recently assisted local Scout association to lay some Turf , it all died we have received some more to lay but I am concerned by the number of grubs in the turf .
Can anyone help to identify these grubs?

I initially thought they might be leatherjacket grubs or chafer grubs, but I'm not certain about this as the colour of the grubs in your photos doesn't seem to match.

They do look like leatherjackets maybe younger and not coloured up.

I would be on to the turf company asap !
Far too many pests to pay for !

Contacted Turf company today and they say it is a Sever Larvae of the Hawthorn fly .
The turf was apparently treated to kill it two days before delivery but will take two weeks for them to die .
So today we continued laying it.
We laid over 200 sq metres last autumn which has all died , turf company providing seed to repair.
Has anyone else had turf laid where they have been advised to treat for pest twice a year , looking like some form of Nematode required.

Interesting , i have seen big hatches of Hawthorn flies when fishing but did not know where they came from !

The only chance they would have of selling that turf to me would be if i was buying bait !

I wonder how selective and effective the treatment is to need retreatment ?

I would try and take as many out as poss. Pity it was treated otherwise  birds would eat them.

I'd tell the turf company you don't want it and to come and take it away. I did that when I received some that was 50% weeds. They gave me a full refund and asked if I would dispose of it as it was too expensive for them to collect. It made lovely compost.
