Witch-hazel cone gall aphid

The witch-hazel cone gall aphid is a tiny insect that lives on witch-hazel bushes. In spring a mother aphid makes the leaf grow a little pointed cone around her, called a gall. The gall is green at first and then turns bright red. Inside it she has food and a safe home.

How fast is it?
Fun facts
The mother makes the gall grow by poking the leaf again and again and putting a special liquid into it.
One mother can fill her gall with about 50 baby aphids, all girls, without needing a father.
The second generation grows wings and flies off to start new families.
At the end of summer the aphids lay eggs on the bark, and these hatch the next spring.
