Honeybee Feces Under the Microscope

Pollens from Honeybee Frass

This is a sample collected from the balcony surfaces of automobiles in Seoul, South Korea.

Transmitted Circular Polarized Light

Definition/Function:

Honeybee fecal pellets (frass) can vary from light yellow to nearly black in color. Honeybee frass consists of pollen grains, wax, and glutamine. They may be dry and cakey, soft and sticky, or slushy depending on the most recent diet and the condition of the bees. These pellets can streak or form globules on the surfaces they land on. The bees defecate in flight so surfaces between the hive and the nectar source may be spotted with these deposits. They are notorious for spotting car finishes in the Spring.

Significance in the Environment:

Characteristic Features:

Honeybee frass contain a variety of different pollen grain, crystals of highly birefringent glutamine, and wax. The wax may also form birefringent crystals but they are not as birefringent as the glutamine crystals.
