title: Data from: Osmia3DNest – novel designed 3D printed artificial nest for solitary cavity-nesting bees

description: The availability and appropriateness of nesting sites significantly
 influence the reproductive success and overall welfare of wild bees.
 Human-induced factors contribute to the destruction of natural nesting
 habitats. To address these limitations, innovative solutions such as the
 development of artificial nests, as indicated in recent studies, offer
 alternative nest sites to support wild bee populations. We
 designed the Osmia3DNest, a 3D printed standardized nest tube for solitary
 cavity-nesting bees, aiming to provide a safety for the environment
 life-long, time-saving, and biodegradable product that anyone can print.
 We proudly present the two Osmia3DNest models for mason bees – closed and
 open – using PLA filament. We demonstrate the effectiveness of
 Osmia3DNest on mason bee reproduction parameters compared with traditional
 reed nests. Osmia3DNest can be an alternative to the other
 artificial nests, which people can customize for their necessity depending
 on their place of living (rural or urban area), and they can also be
 washed and reused several times and then decomposed. Osmia3DNest
 holds potential for wildlife biologists, management of pollinators, and
 educational outreach, offering adaptability for different bee species and
 experimental needs.

 [https://doi.org/10.5061/dryad.547d7wmh0](https://doi.org/10.5061/dryad.547d7wmh0) The data include results from field experiments comparing the morphometric and reproduction traits of *Osmia rufa* in natural and 3D-printed nests. We designed the 3D-printed nest for the solitary bee *Osmia rufa* made of PLA filament. In presented study we tasted two types of nests: open “3D open nest” and closed one “3D nest” and traditional used reed stem nests. The first experiment was conducted on 3D printed nests with similar dimensions (7.0 mm diameter and 150.00 mm length). After incubation in laboratory we compared such parameters as the occupation of nests by bee, sex ratio, the mass of cocoons, and number of cells and cocoons. In the second we compared the number of adult individuals and sex ratio between 3D nests with three internal diameter sizes: 7 mm, 8 mm, and 10 mm. ##### Description if the data and file structure  The data are summarised in the single excel file containing different tab of different datasets.
