These eggs were found on a leaf of my lemon tree. I figure they are the eggs of some pest of some kind so they have been removed. I tried to do a search to find out what they might be the eggs of, & could only find the "bronzed orange bug" or "stink bug". In the pics I found, the eggs were green, not brown like these, and somewhere I read that they always lay 14 eggs, which I find hard to believe. There is also something called the "Horned Citrus Bug" which also is a pest. Anyway, whatever these eggs are the babies of, they are no longer on my tree and can do no more damgage to it.
