To be fair, we probably all worried about these 'eggs' at the beginning of our gardening lives, and new gardeners cannot be expected to know what it is. We had people to answer us, so let us be decent and explain to the newer generation. Of course the same things will come up year on year, that's the nature of what we do. Thank goodness there are new gardeners coming along to ask the old questions, and thank goodness there are we old fogeys around to anser them - long may it last.
Amy-new-at-this, thank you not only for asking the question, but for sending decent clear pictures of what it was you wanted identified, that makes it all so much easier, from eggs to leaves. Continue to garden and to love it, there is nothing better on this green earth that trying to keep it that way.
