My little aphid, how many wings have you when you have any?
Yes, little Nell, they have four of the daintiest, prettiest little wings you ever saw.
True enough, most of them have no wings at all.
John thinks those must be young ones.
Sometimes they are, but not always. Many of the adult aphids have no wings.
The aphids are very curious insects, and when you are older I hope you will remember to study them carefully.
No, John, not all species of aphides make honey dew.
Some form instead a white, powdery substance that is seen scattered over the body.
