OMG, I have found that most of my big tomatoes are being attacked by giant catapillars. they have layed black eggs, like the ones that you get on nastertiums but they are at least an inch long when tuned into catipillare. I have picked off all I can see and as they have eaten into the tomatoes, have lost loads. I have taken them out of the greenhouse and put the plants outside. Not expecting much from them but at least the small tomatoes might have a chance in the greenhouse. I only hope I am not too late. ???
