I haven’t had much luck with growing Brassicaceae (/ˌbræsɪˈkeɪsii/) or Cruciferae (/kruːˈsɪfəri/), commonly known as the cabbage family. （十字花科中文名譯自舊稱Cruciferae）
You can imagine how proud I was to see my pakchoy growing so well this time.
A week later, this is what’s left of them.
Finally figured out the culprit, culprits as I think there are two types of worms.
The top three are Cabbage worms I believe. The one on the bottom right of the picture is a different type of work, I guess is cabbage loopers. Unlike cabbageworms, cabbage loopers raise and lower their bodies as they move. Cabbage worms become cabbage white butterflies, which are mostly white with a few black markings. Cabbage white butterflies might seem like a pretty addition to the garden, but they are probably laying eggs on the undersides of leaves.
