Osmia leaiana is a solitary Wildbienenart the genus genus Osmia from the group of wall bees (family Megachilidae).

features

female

The females are between 9 and 10 millimeters in size. They have a black body, the tergites of the abdomen sometimes with a more or less metallic blue or green sheen. The hair is whitish except for the bright orange-red belly brush. The hair ties on the top of the abdomen are sparse and indistinct. The mandibles are thickened at the base, with a central rib, and at the base with a rising corner. The scutellum and the middle field of the propodeum are very shiny, the rest of the propodeum is matt due to the dense dots. The species is indistinguishable from related species, especially Osmia niveata in the field and in photos. Species feature is: The front edge of the clypeus has two (occasionally only one) protruding humps in the middle, it is not edged.

male

The males have a metallic greenish or blue shiny body with red-brown hair. Their size is between 8 and 10 millimeters. The first sternite of the free abdomen has no special formations such as protruding lamellae or cusps. The middle field of the pronotum is smooth and shiny and very clearly set off from the matt side fields. They are also indistinguishable from related species in the field.

distribution

Their distribution extends in Europe to the north up to the 64th north latitude . It is distributed to the south as far as North Africa. Osmia leaiana colonizes almost the entire Palearctic , from the Atlantic in the west to the Pacific ( Khabarovsk region ) in the east. The species is specified from Turkey, northern Iran, Kazakhstan and Yakutia.

ecology

Osmia leaiana nests in existing tunnels in dead wood and in hollow plant stems, it also colonizes holes in artificial nesting aids. She prepares cell walls and nest closures from chewed leaves. For pollen, it specializes in daisy family (Asteraceae), where it is mainly indicated by red thistles and knapweeds. The flight time of the species ranges in Central Europe from about May to August.

Cuckoo bees

Your cuckoo bees are Stelis phaeoptera and possibly also Stelis punctulatissima .

Taxonomy

The species was first described as Apis leaiana in 1802 by the English entomologist William Kirby. Within the genus Osmia , Osmia leaiana is included in the subgenus Helicosmia . Synonyms are Apis hirta Geoffroy, 1785 (nec cabinet, 1781), Apis ventralis Panzer, 1798, Osmia atra Schenk, 1853, Osmia confusa Morawitz, 1869, Osmia solskyi Morawetz, 1870, Osmia truncatula Thomson, 1872, Osmia bidens Pérez, 1879, Osmia forsii Alfken, 1924. Two subspecies are distinguished:

  • Osmia leaiana leaiana
  • Osmia leaiana schachti

The subspecies schachti was described by Klaus Warncke as Osmia ventralis schachti after material from Morocco ( Oukaïmeden ) and is only known from there.
