Cabbage white decoy

Having only 8 psb plants I don't want to go to the expense of buying more netting so have covered them with netting i have of about 8mm squares. While I don't expect this to keep out the butterflies I do have a few plants left over and was thinking of planting them close by to act as a decoy thus attracting the butterflies to an easier target. Does anyone think this will work?  I have nasturtiums in another area. TIA

The pigeons would have mine, if there were unnetted, before caterpillars had a look in!

Not sure it would help that much.

If you can get down the plot fairly often, 8 plants should not be a huge job to check over regularly for eggs or larvae. ?

I has 8 plants last year unnetted,what a bleeding nightmare that was!thought I was getting all the eggs off and next day caterpillers everywhere!!.
