Workers then compact the pollen. storing each variety in an individual wax hexagonal cell , typically located within their bee brood nest. This creates a fermented pollen mix call beekeepers call 'bee bread'. Dry ...
A pollen count is a measurement of the number of pollen grains in a given volume of air. Pollen counts, and forecasts of pollen conditions, are routinely produced and reported to the public because high aerial pollen concentration is associated with increased rates of allergic reaction for those with conditions such as hay fever and asthma .

Pollen of T. populnea viewed under a light microscope. The Portia tree reaches a height of 6–10 m (20–33 ft) tall and its trunk can measure up to 20–30 cm (7.9–11.8 in) in diameter. [20] It grows at elevations from sea level to 275 m (902 ft) [21] in areas that receive 500–1,600 mm (20–63 in) of annual rainfall. [10]
