A sugary secretion emitted by most insects that have developed mouthparts and feed on the sap of plants. Bees use honeydew to produce honey in environments where there is limited availability of nectar plants. Honeydew honey has a color ranging from dark amber to almost black, sometimes with a greenish tint; it remains liquid for a long time; and it is very sticky and rarely crystallizes completely. It has a medium intensity aroma and taste, and the flavor is slightly sweet and persistent.
