Aphid

From BonsaiWIKI

Tiny soft-bodied insects whose color ranges from light green through black. Sometimes winged. Size ranges from 1/6 inch to nearly invisible. These insects group in clusters on the stems and leaves of bonsai, favoring succulent new growth.

Aphids feed by sucking the sap of trees and shrubs. Affected leaves may yellow or curl.
