tiny grub nestling in frothy saliva 'nest'!

I've just found a few of these in my London garden - they are pale green/yellowish and about 2mm long. I think they are grubs or caterpillars...I only noticed them at all because they seem to exude a weird, frothy spit-like substance in which they sit, if that makes sense, usually in the join of two branches (noticed them in my shrub roses and sedum green roof mainly).

I propmptly squished them in disgust.

What are they?

    Cuckoo spit bug.

    Don't know their name but as M says the froth is called cuckoo spit and the bug develops in it. They don't usually do any harm to the plant.. You can squish them if you want or I wash off or rub off.

    Ohh I know this one, it is cuckoo spit , it was on Springwatch tonight...it makes the spit from its bottom to protect it as it tastes bitter...

    The little bug in the Cuckoo Spit is called a Froghopper - they talked about it on Springwatch this evening.

    No-one knows if you've done your housework, but everyone knows if you've done your gardening !

    Froghopper- same thing as cuckoo spit bug I think. They don't really do any harm Jess. You can spray them off with the hose.

  • oooooh! you're all so knowledgable!

    so if they're harmless to the plants  (must be a first in my pest-ridden garden) should I be ecofriendly and leave them be?!

    Yes! image

    If you don't like the look of them  a jet of water from the hose or a hand held squirty thing sees them off the plants image

  • Hello! Spraying the froghoppers with  jet of water isn't really a very friendly thing to do... the 'spit' is protecting the nymphs while they develop. They don't do any harm to plants at all so if you want to let them get on with being froghoppers, it's best to just leave them be. image

    They are sap suckers so while one on a plant may do little harm, a major infestation would weaken the plant.

  • aaah thanks Berghill - I had wondered...
