Nist - and observing the aid for wild bees and solitary wasp for the observation and photographic documentation of the incubation process of wild bees and solitary wasp. (1, 2 and 3) characterized in that a, with a groove (1) and is of round hard wood base body (2) over its entire length in a slotted (5) plastic - or acrylic glass sleeve (3) is inserted, which is dimensioned such that as a result of its own spring force the hard wood base body and thus firmly encloses seals off the groove in a form-fitting manner. The hard wood base body is at its rear end with a wood disk (4) is tightly sealed. With regard to the materials used, the dimensions and type of use, empirical values flow in the technical development in the form of additional improvements.
