The alarm pheromone emitted when a bee stings another animal smells like a banana. [5] [6] Drone bees, the males, are larger and do not have stingers. The female bees (worker bees and queens) are the only ones that can sting, and their stinger is a modified ovipositor.
When it rains, the bees can get wet. If the bee is in a burrow, it may simply drown. If the bee is underneath something, when night comes, the bee may freeze to death due to the low temperatures in the desert. Since these bees are solitary, they don’t have the protection of a hive or colony; thus, they are more susceptible to the elements. [11]
When it is time for females to lay their eggs, they add pollen to each brood cell and lay one egg in each cell next to the pollen. [20] The sequence of nesting behavior is: cell construction, provisioning, egg-laying, and sealing the cell. [15] A cross-sectional view of an O. bicornis nest: Partitioned cells can be seen in a tube.
A leaf-cutter bee showing abdominal scopa. Megachilidae is a cosmopolitan family of mostly solitary bees.Characteristic traits of this family are the restriction of their pollen-carrying structure (called a scopa) to the ventral surface of the abdomen (rather than mostly or exclusively on the hind legs as in other bee families), and their typically elongated labrum.

Megachile rotundata, the alfalfa leafcutting bee, [1] is a European bee that has been introduced to various regions around the world. As a solitary bee species, it does not build colonies or store honey, but is a very efficient pollinator of alfalfa, carrots, other vegetables, and some fruits.
In the case of a bee sting, he recommends making sure the stinger is removed — use the back of a knife to scrape it off rather than tweezers, which can pinch the stinger and release more venom ...
The researchers said their findings could have implications for pollination and conservation strategies for bees and plants. Social bees ‘travel greater distances for food than solitary ones ...
It is believed that because solitary bees have very large, lipid-rich eggs the pollen provides the lipids and amino acids required for making these eggs. Pollen consumption is larger in younger females, and primarily occurs in the afternoon and evening as pollen collected early in the day goes toward larval provisioning.
