Plastic drink straws are fantastic material suitable as a standardised trap. It offers exactly same living space and conditions. We have found two sizes of straws (5 and 8 mm in diameter), which diversifies conditions and can be acceptable for at least some from almost 700 species of solitary bees living in the Czech Republic.

We want to install five wooden traps (each with the same number and colour of straws) at all three localities for quantitative comparison of solitary bee population density. It can be compared both with activity of our monitored honey bees and landscape diversity.

Just after preliminary installation of bee shelter prototype the first serious applicant has appeared – the most curious alpaca Maya.
