I found these eggs on an ornamental conifer in my garden on 6/6/2014 and the 1st photo was taken on that day. I have been watching them periodically since then. The 2nd photo was taken 6 days later on 12/6/2014. I don't know when they started to hatch but I found them 7 days later on 19/6/2014 (to-day) with most appearing to have hatched and a few eggs left. The 3rd and 4th photos were taken then.
They measured approx 10mm along their longest row.
