Tetragonisca angustula flora availability. "T. angustula" honey contains more moisture than honey from typical honey bees and is also more acidic, giving it a complex flavor.

Honey and propolis gathered from different geographical areas have different chemical compositions yet they all exhibit some type of antibacterial activity. Another bee, "Apis mellifera", produces honey and propolis with very similar qualities. Forests are being

At this point the plate is set aside without clamps, and the hide glue
