aphids |
|
Aphids excrete a sugary waste produce called honeydew. Notice the clear drop on the left side of this picture. Ants, bees, and wasps collect honeydew for food. Black and brown fungi, appropriately called sooty molds, cover leaves and other objects below aphid colonies where honeydew collects. |

giant bark aphid |
Longistigma caryae |
As aphids feed, they excrete a sticky, clear liquid known as honeydew that often forms a sticky coating on automobiles, picnic tables, lawn furniture, and plants underneath plants where aphids are feeding. A gray-black, sooty mold soon begins to grow on the sugar-rich honeydew, and it not only blocks sunlight and disrupts photosynthesis, but it can damage the finish on cars, chairs, tables or other objects. |
