Pollen beetle it is not adapted to attract or feed pollinators. Furthermore, as an adaptation to being borne effectively by the wind, anemophilous pollen must be very light. 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
Tylosis (botany) then dies as its contents are disgorged into the empty space of the dry vessel and highly effective decay-inhibiting substances, notably tannin, are formed and absorbed by the adjacent vessel walls. Tylosis (botany) A tylosis (plural: tyloses) is a bladder-like distension of a parenchyma cell into the lumen of adjacent vessels in wood. Less certainly, the term tylosis is in use to summarise the physiological process and the resulting occlusion in the xylem of woody plants as response to injury or as protection from decay in heartwood. It is a key process in wall one of the Compartmentalization Of Decay
