Megachilidae is a cosmopolitan family of mostly solitary bees. Characteristic traits of this family are the restriction of their pollen-carrying structure to the ventral surface of the abdomen, and their typically elongated labrum. Megachilid genera are most commonly known as mason bees and leafcutter bees, reflecting the materials from which they build their nest cells ; a few collect plant or animal hairs and fibers, and are called carder bees, while others use plant resins in nest construction and are correspondingly called resin bees. All species feed on nectar and pollen, but a few are kleptoparasites, feeding on pollen collected by other megachilid bees. Parasitic species do not possess scopae. The motion of Megachilidae in the reproductive structures of flowers is energetic and swimming-like; this agitation releases large amounts of pollen.
Mason bee is a name now commonly used for species of bees in the genus Osmia, of the family Megachilidae. Mason bees are named for their habit of using mud or other "masonry" products in constructing their nests, which are made in naturally occurring gaps such as between cracks in stones or other small dark cavities. When available, some species preferentially use hollow stems or holes in wood made by wood-boring insects.
Osmia lignaria, commonly known as the orchard mason bee or blue orchard bee, is a megachilid bee that makes nests in natural holes and reeds, creating individual cells for its brood that are separated by mud dividers. Unlike carpenter bees, it cannot drill holes in wood. O. lignaria is a common species used for early spring fruit bloom in the United States and Canada, though a number of other Osmia species are cultured for use in pollination.
Jacobaea maritima, commonly known as silver ragwort, is a perennial plant species in the genus Jacobaea in the family Asteraceae, native to the Mediterranean region. It was formerly placed in the genus Senecio, and is still widely referred to as Senecio cineraria; see the list of synonyms (right) for other names.
Anthidium is a genus of bees often called carder or potter bees, who use conifer resin, plant hairs, mud, or a mix of them to build nests. They are in the family Megachilidae which is cosmopolitan in distribution and made up of species that are mostly solitary bees with pollen-carrying scopa that are only located on the ventral surface of the abdomen. Other bee families have the pollen-carrying structures on the hind legs. Typically species of Anthidium feed their brood on pollen and nectar from plants. Anthidium florentinum is distinguished from most of its relatives by yellow or brick-red thoracic bands. They fly all summer and make the nests in holes in the ground, walls or trees, with hairs plucked from plants.
Osmia cornuta, the European orchard bee, is a species of bee in the genus Osmia.
Anthidium florentinum, one of several European wool carder bees, is a territorial species of bee in the family Megachilidae, the leaf-cutter, carder, or mason bees.
Anthidium manicatum, commonly called the European wool carder bee, is a species of bee in the family Megachilidae, the leaf-cutter bees or mason bees.
Anthidium maculosum is a species of bee in the family Megachilidae, the leaf-cutter, carder, or mason bees. It is a solitary bee where the males are territorial and the females take part in polyandry. The males of A. maculosum differ from most other males of bee species because the males are significantly larger than females. In addition, subordinate males that act as satellites are smaller than territory-owning males. This species can be found predominately in Mexico and the United States.
Coelioxys, common name leaf-cutting cuckoo bees or sharp-tailed bees, is a genus of solitary kleptoparasitic cuckoo bees belonging to the family Megachilidae.
Megachile leachella, also known as the silvery leafcutter bee, is a species of solitary bee in the family Megachilidae. This species is widely distributed in the Western Palaearctic region from Southern Fennoscandia to North Africa and the Middle East, however the precise boundaries of the species range is not fully understood. The species was described by John Curtis in 1828.
Megachile centuncularis, commonly known as the patchwork leafcutter bee, is a species of bee in the family Megachilidae. It was first described by the Swedish naturalist Carl Linnaeus in 1758.
Osmia caerulescens, the blue mason bee, is a species of solitary bee from the family Megachilidae. It has a Holarctic distribution extending into the Indomalayan region, although its presence in the Nearctic may be due to human-assisted introduction.
Osmia inermis, the mountain mason bee , is a species of mason bee from the family Megachilidae which has a Holarctic distribution.
Hylaeus communis is a Palearctic species of solitary bee.
Anthophora bimaculata is a species of bee.
Pseudoanthidium tenellum is a species of bee in the family Megachilidae.
Tetraloniella dentata is a species of bees within the genus Tetraloniella.
Trachusa byssina is a species of bees within the genus Trachusa.
Sichel's bumblebee is a species of bumblebee.
