"Intention of the website
The “Palaearctic Osmiine Bees” website intends to give a concentrated but concise overview on taxonomy, distribution, nesting biology and flower preferences of all osmiine bee species known to occur in the Palaearctic region. Scientific basis for the data on taxonomy and distribution is the recently published “Taxonomic catalogue of the Palaearctic bees of the tribe Osmiini” (Ungricht et al., 2008). The biological data are based on an extensive literature study on osmiine nesting biology (A. Müller, C. Praz, J. Neff, G. Le Goff and C. Sedivy, unpublished), on a compilation of flower records from the literature (A. Müller, unpublished) as well as on results of ongoing pollen-analytical studies at the Entomological Collection of the ETH Zürich. The information for each species will be updated and corrected in regular intervals. Important new findings or major corrections will be communicated and justified in the “Updates and Corrections” part of the website. Here, all interested readers are invited to scientifically comment on new entries by using the blog facility of the website.

To keep all bee taxonomists and biologists up to date, new synonymizations and lectotypifications will also be communicated, even if they are not yet published and therefore not valid under the terms of the rules of zoological nomenclature.

In addition to the species and genus accounts in the “Catalogue of Palaearctic species”, introductory pages treat Phylogeny and Classification, Biogeography, Diversity, Biology, Taxonomy, Faunistics and Fossil taxa in a more broader context, including osmiine taxa from outside the Palaearctic as well.

Plea for collaboration
Knowledge on the taxonomy, distribution and biology of the Palaearctic osmiine bees is still in a rather poor state. Therefore, the “Palaearctic Osmiine Bees” website is a construction site that needs to be continuously complemented with new information. Readers willing to share new distributional data, biological observations, pictures or unidentified osmiine material are warmly acknowledged.
