This here is a cabbage moth. Or cabbage butterfly. Or cabbage butterflymoth.
The 'experts' seem vague on the terminology. I prefer to think of them as moths.
I like butterflies.
But I get lots of them fluttering around the garden and, I grant you, they look very pretty.
Except...the little blighters lay eggs on my cabbages and Chinese greens; the next thing I know I have multilegged green stomachs devouring my garden.
Now, on one of these oh-so-green gardening sites, someone gentle soul suggested spreading broken eggshells around the cabbages because the moths are short-sighted and socially considerate and, if they think some moth got there first, they will stay away.
The favourite hiding place in my garden at the moment is the broad beans; the flowers bear some considerable resemblance to both moths and broken egg shells.
I have been using derris dust but I am told this is environmentally dodgy. I believe there is a bacterial soup you can use and I will investigate that.
In the mean time...
I play moth tennis with a plastic sieve.
Low impact on the environment, high impact on the moth.
