Ye Olde Cauliflower & Guests

I planted this cauliflower last year.
It provided one small head of cauliflower. I had thought to remove it and plant some new ones. However, it seemed quite robust and survived the summer. I didn't tend to the garden during the warmer months.

Now, being deep into Autumn. I guess we are truly entering winter as the air has become much colder.

Today, I noticed a little head of cauliflower tucked within the midst of the leaves.

It would be great to have another gift to add to a soup.

These little coccooned friends were under a leaf.
Quite a beautiful clutch of eggs, or cocoons.

With a little research, they could belong to the Diamondback Moth.

The larva & eggs seems to match the info sheet.
