Honey bees take resins from tree buds and mix it with wax to produce a sticky substance they use to coat surfaces in the hive and to seal small cracks. In this form it is called propolis.
Bees also collect resin from trees but they don't eat it but turn it into a sticky substance called propolis which they use to fill small holes and 'glue' things together.
Some special glues use sap from trees.
Acacia
Yes. Bees pollinate most flowers and trees. One of a bees favorite places is a orchard where fruit trees are everywhere.
we have 550 olive trees in northern CA and no bees.
The best thing that humans can do for honey bees is to plant bee-friendly flowers, shrubs and trees and not use insecticides.
Glue is typically derived from natural substances found in trees, such as sap or resin. The sap is collected from trees like pine, spruce, or fir, and processed to create different types of adhesives, like wood glue or construction glue. These adhesives are then used for various purposes like binding materials together.
Fruit trees attract bees when in bloom. Bees are also attracted to the sweetness of the fallen fruit. Apple, peach, pear, and cherry for example. Threr are always millions of honey bees that visit my plum and crabapple trees to collect pollen. (I live in North Carolina.)
they let bees build hives in them
Honey bees.
Apple farmers need bees to pollinate their apple trees. Where bees have been eradicated by pesticides, more bees, or hand pollination, are necessary for the trees to bear fruit.
No, honey bees typically make hives above ground in structures like trees, caves, or man-made beehives. Ground-dwelling bees like mining bees or sweat bees may create nests underground, but honey bees do not.
