I went to pick a cabbage yesterday and noticed eggs in my cabbage leaves where they join the plant. They are also on the broccoli plants in the same place and in the lettuce near the ground where the leaves are joined. They are small clusters of black eggs. Each egg is round in shape and maybe 1/2 the size of a bb or smaller, but there are many in a cluster. There are many clusters on each plant. I did a google search, but can't seem to find a picture to identify them. Does anyone have an idea of what they are? We are in the midst of a drought and extended hot weather. I live in Northern Wi. We have had many days of temps in the high 80's - low 90's and very little rain. I've been watering regularly from both a sprinkler and soaker hoses. Oh-- the leaves on the cabbages and broccoli have small holes too. I've never really had pest problems in the garden, so I don't know what I'm dealing with. Thanks!
