Often we have no idea what is happening up in the canopy of our trees. Insects are born, live and die with us being none the wiser. However, one group of insects often give themselves away in a rather annoying way – by defecating, a lot. Aphids and their plant feeding relatives are so well known for their excrement that we have even come up with a more pleasant term for it – honeydew. Honeydew is produced by aphids and soft scales and is basically the plant sugars that end up passing through the digestive system of sap feeding insects.
