That's great Martin. We were wondering about this a couple of weeks ago after watching a piece of video somewhere. I like the link with the underground pupal cell section - maybe the pale sides I am looking for.

I was troubled with this ID because the eggs were under the leaf skin and different to the eggs that the beetle is laying.
I have found another ID for this spotting - sawfly eggs. These are known to be laid into the leaf and is more likely to be accurate. See pic #3

Hey, I've finally stumbled upon the ID of these (apparently hatched) eggs. It's a paropsine leaf beetle. They also seem to be placed under the leaf skin membrane.

Fascinating ! - looks like whatever it is has separated the waxy coating from the upper epidermis to lodge its eggs? - for protection, perhaps. I like the rim of the leaf that has been left intact. Great spotting and photos, Martin.
