Insect hotel in Helmsley, UK. Hotels should be relatively close to flowering herbs, wild flowers and native shrubs and trees to cover the food needs of the insects. Photo by Munki Munki, www.flickr.com.
Rovarszálló Helmsley-ben, az Egyesült Királyságban. A szállóknak aránylag közel lenniük gyógynövényágyásokhoz, vadvirágokhoz és őshonos cserjésekhez, fákhoz, amelyek a rovarok táplálékát biztosítják.
Solitary bees are different from social bees (such as honey bees) in that every female is fertile and makes individual nest cells for her offspring. Some native bees are ground nesters but more than 30% are wood nesters. The female wood nester will look for pre-existing cavities such as hollow stems or holes in wood that are just the right size to use as a nest.
The female typically creates a series of compartments (cells) and within each cell she will lay an egg on top of its future food source. The female bee will make numerous foraging trips to flowers collecting pollen and nectar that she will pack into each cell. It is on these trips that the female wild bee acts as a pollinator for plants and food crops. It can take anywhere from 20 to 30 trips to fill each cell with food. When she is satisfied with the amount of food, she lays an egg, compartmentalizes the cell, and moves on to creating the next cell. When she feels the chamber is complete, she seals off the end, and moves on to filling a new chamber. The last cells (those closer to the opening) contain eggs that will become males, as males hatch before females. Although each species is different, mason bee females live for about a month, and can build a cell nest for about two eggs every day. The larva hatches from the egg after a week or more and begins to eat the provided pollen and nectar. After the food has been eaten, the larva spins a cocoon and pupates within the cell. By the end of summer or early fall, the bee transforms but remains in the cocoon as an adult throughout the winter. In spring, the males begin to emerge by chewing their way out. The females, which are almost always in the deeper cells of the tunnel, emerge a week or two later.
While solitary females each make individual nests, some species prefer to make nests near others of the same species, giving the appearance to the casual observer that they are social. Nest photo by Mike N. of Vancouver, BC.
