Allotments 4 All

Something is eating my courgettes and it is not a slug.  The leaves are full of very small holes like green lace.

I would suspect a green fly or three hundred but I can see nothing on the leaves.  Never had this in courgettes before.

Any ideas would be appreciated.

Flea beetle?

What size are the plants?

Slugs went for my courgette plants and the effect was to take away the green stuff and leave a lace like structure behind.

I agree, slugs and snails rasp at leaves and can leave a lacy effect. It pobably just had an interrupted meal! Hopefully by a bird that ate it.....

I put a ring of plastic bottle around the stem of all squashes when I plant them out, it helps prevent the slimies knawing through the main stem which means you lose your whole plant.... :-\

Sorry for not getting back, lost the thread. 

Oh no it is definitely not slugs.  Lost a lot of things in my time to slugs.  Firstly they a visible in the dark.  If they get in the boxes of seedling sooner or later I will track them down.

Some of them are large plants.  I think it may be ants.  There are a lot of red ants about this year in my garden.  Though I did not know ants ate courgette leaves.

Flea beetle when do they eat the plants.  Cannot see anything.  The results look a bit like greenfly but no fly green or otherwise.
