Ants building a structure up a rose bush

Hi All, 

I’m not a gardener by any stretch I just try to keep things alive and take part in growing the biggest sunflower I can every year to compete with a friend of mine. 

But this year I found what looks like an ants nest being built on the stems of a rose bush, it’s like they are encasing the plant. 

I have never seen this before just wondering what it’s called been looking on the Internet and can’t seem to see any reference to this kind of structure. 

I have asked a few keen gardeners too and they think it’s rather strange.  

Any advice would be greatly received. 
Cheers Iain

    I've had similar with strawberries.  Mine were full of eggs/pupae, so I suspect it was a response to a nest flooding event following heavy rain.  They were gone in a few days.
    A trowel in the hand is worth a thousand lost under a bush.

    If you have ants it means your soil is too dry.  Give the bed a good soaking and the ants will move.

    I agree,  wash off with a strong jet. Do the Roses suffer from aphids or scale insects,  these will attract ants as they feed on the honeydew.

    I'm not sure about it being too dry. This has been a very wet summer and I have never seen so many ants in the garden before.

    This is what I have always sworn by, but whilst working in the garden where I volunteer today, and there were two huge ants nests in heavy clay. It seems they aren't anywhere near as fussy as I thought!

    We’ve had lots of rain lately and I’ve still got ants on clay…..sodden soggy clay.
