Insects can produce the honeydew sooty molds

Fungi that most commonly cause sooty molds in garden and landscape situations are in the genera Capnodium, Fumago, and Scorias. Less common genera include Antennariella, Aureobasidium, and Limacinula. The species of sooty molds present are determined by a combination of the environment, host, and insect species present. Some sooty mold species are specific to particular plants or insects, while others might colonize many types of surfaces and use honeydew produced by several kinds of insects.
A number of insects can produce the honeydew sooty molds need for growth. Their common characteristic is that they all suck sap from plants. The insects include aphids, leafhoppers, mealybugs, psyllids (including eucalyptus lerp psyllid), soft scales, and whiteflies. Both the immature and adult stages of these insects feed by sucking sap from plants, producing honeydew.
