So far I have found about 8 different insects on my cabbage. Most abundant are eggs from the cabbage white butterfly Pieris rapae. These individual yellow eggs are stuck to the undersides of leaves. Butterflies are pretty mobile but it is amazing that I have cabbage aphids already. I also found whiteflies. So far there are just a few of everything so I am waiting to see who else arrives and who really becomes abundant and damaging to my cabbage plants.
