January Quiz 2005

You were given an English ivy for a house-warming present. You set it in the living room next to a window so it would receive plenty of light. After a couple of months, you notice that the leaves have lost the lush green color they had when you first received it. When you look more closely, you notice there is webbing covering some of the foliage. When you turn the leaves over and use a hand lens you see some very small creatures crawling around.
