Very similar to "manna", as referred to in the Old Testament: "In the Biblical account, the name manna is said to derive from the question man hu, seemingly meaning "What is it?";[14] this is perhaps an Aramaic etymology, not a Hebrew one.[13] Man is possibly cognate with the Arabic term man, meaning plant lice, with man hu thus meaning "this is plant lice",[13] which fits one widespread modern identification of manna, the crystallized honeydew of certain scale insects.[13][15] In the environment of a desert, such honeydew rapidly dries due to evaporation of its water content, becoming a sticky solid, and later turning whitish, yellowish, or brownish;[13] honeydew of this form is considered a delicacy in the Middle East, and is a good source of carbohydrates.[15] In particular, there is a scale insect that feeds on tamarisk, the Tamarisk manna scale (Trabutina mannipara), which is often considered to be the prime candidate for biblical manna.[16][17]"
