Today I found clusters of dull brown eggs on two of my tomato plants - one in the greenhouse, the other outdoors. They were on the top side of a leaf, arranged in a tight-packed honeycomb pattern, looking very like butterfly eggs apart from the colour. Never had this problem before. Anyone know what they are? Sorry, couldn't take a photo and, frustratingly, can't find a picture online either. I live in the West Midlands, England.
