Osmiini is a tribe of leafcutter, mason, and resin bees in the family Megachilidae. There are about 19 genera and at least 1,000 described species in Osmiini. [1] [2] [3]
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.
Megachilinae is a subfamily of bees, the largest subfamily in the family Megachilidae, and includes mason bees, leafcutter bees, and carder bees.
Heriades is a genus of bees in the family Megachilidae. Fairly small and usually black, they are found all over the world. There are more than 130 species worldwide, roughly 25 species in North and Central America, but only 3 species are native east of the Rocky Mountains. European species such as H. truncorum can be found on the east coast of the US. Like other bees in the tribe Osmiini, Hoplitis and Ashmeadiella, they nest in cavities in wood excavated by other insects, or perhaps occasionally pine cones. They separate the cells of their nest with resin .
Hoplitis anthocopoides is a species in the family Megachilidae, in the order Hymenoptera . The distribution range of Hoplitis anthocopoides includes Africa, Europe, Northern Asia, and North America.
Triepeolus is a genus of cuckoo bees in the family Apidae. There are at least 140 described species in Triepeolus. The majority of species whose life history is known are kleptoparasitic in the nests of bees in the tribe Eucerini, especially the genera Melissodes and Svastra.
Calliopsini is a tribe of mining bees in the family Andrenidae. There are at least 120 described species in Calliopsini.
Anthidiini is a tribe of insects in the family Megachilidae. There are at least 40 genera and 840 described species in Anthidiini. There is strong evidence that the tribe is monophyletic.
Conanthalictus is a genus of sweat bees in the family Halictidae. There are about 13 described species in Conanthalictus.
Lithurgopsis is a genus of northern cactus woodborers in the family Megachilidae. There are at least nine described species in Lithurgopsis.
Sapyga louisi is a species of a club-horned wasp in the family – Sapygidae. Adults feed from flowers and the larvae are kleptoparasites of leaf cutter bee larvae, including those of Heriades carinata.
Dianthidium simile is a species of leafcutter, mason, and resin bees in the family Megachilidae. It is found in North America.
Dianthidium is a genus of leafcutter, mason, and resin bees in the family Megachilidae. There are at least 20 described species in Dianthidium.
Stelis interrupta is a species of cuckoo bee in the family Megachilidae. It is found in North America.
Stelis is a genus of kleptoparasitic cuckoo bees in the family Megachilidae. There are at least 100 described species in Stelis.
Osmia foxi is a species of mason bees in the family Megachilidae. It is found in New Mexico and southeastern Arizona in the United States and in Sonora, Mexico.
Myrmelachistini is a tribe of ants in the family Formicidae. There are at least 2 genera and 50 described species in Myrmelachistini.
Ashmeadiella is a genus of bees in the family Megachilidae. There are more than 60 described species in Ashmeadiella.
Hoplitis is a genus of bees in the family Megachilidae. There are more than 380 described species in Hoplitis.
Protosmia is a genus of subgenus Chelostomopsis in the family Megachilidae. There are more than 30 described species in Protosmia.
