More specifically than speaking loosely of "pollen beetles" as a common name the expression is the common name for certain species of beetle in particular, mainly a few members of the families Melyridae, Nitidulidae and Oedemeridae. However, there are many others that, though not commonly called "pollen beetles", do feed avidly on pollen, including species in the following: Among the Melyridae the most prominent example of a species commonly referred to as a pollen
Gum (botany) in western North America. Gum (botany) Gum is a sap or other resinous material associated with certain species of the plant kingdom. This material is often polysaccharide-based and is most frequently associated with woody plants, particularly under the bark or as a seed coating. The polysaccharide material is typically of high molecular weight and most often highly hydrophilic or hydrocolloidal. Many gums occur as seed coatings for plant species; the adaptive purpose of some of these gummy coatings is to delay germination of certain flora seeds. An example of such a gummy coating occurs in the case of Western poison
