Visitors to my blog have mentioned the Tomato Moth this year.
It seems we may have to be very vigilant this season, I have never seen so many of the Caterpillars. If you want to be Organic, vigilance is the only thing I know of to beat this stealth fiend.

Looking at the photograph below (Right Click and select View Image for full size) several holes can be seen in the leaves, some no more than pin holes.

The felons who created the holes are just hatched and no more than 1mm long, its an easy job to rub them between leaf and finger to destroy them. If left to develop they would devastate the plants completely.
