What are these eggs on my rocket?

[TheChosenTwo]

Will take a while for my photo to upload I guess but there are teeny yellow eggs growing on the underneath of my rocket - can anyone identify the eggs?!

Cabbage White butterfly eggs

Definitely butterflies

Oh wow, really?!
oh no, I had cut the rocket before I spotted it and now the leafs are lying on the edge of the veg bed, how long until the eggs hatch do you think? I don’t want to disturb them because it will probably damage them but now I’ve essentially killed their leaf it’s only a matter of time before it shrivels up and perishes and it’s been lovely this year seeing the odd butterfly in the garden. Ffs!!!
