The Knox Cellars Observation Box makes it possible to observe the female Mason Bees laying her eggs and building cocoons. One surface of the box is a weather safe clear panel with a sliding door covering the panel. The box may be mounted horizontally or vertically to a wall.
The liner tool is used to easily push the liner containing Mason Bee cocoons out of their tubes when harvesting them for storage, no paper tubes are needed. This observation box is a great teaching tool for children learning about Mason Bees.
