It is easy to just look the other way when a Cabbage White flies by because they are so common and typically plain. However, there is often so much more than we see with the naked eye.
which provides a really good overview of the Small White vs. the Large White vs. the southern version of the Cabbage White. It is really interesting. The key field marks to notice are the size of the butterfly, the darkness of the dots and the size of the outer dark marks on the topside of the forewing. There will likely be more opportunities this season to see more.
