But do the bees raise their eyes while flying forward in the dark? We placed the Megalopta nest, which is a hollowed-out stick, at a stand in the forest. Sandra Chaib, a University of Lund doctoral student who worked on the project. On both sides of the nest, we placed two additional mock nest sticks which we had drilled holes in to resemble nests. Above each nest, they placed a distinctive visual landmark: a single black bar to mark the real nest and a pattern of stripes in different orientations above the fake nests. The bee was allowed to forage for a few nights to get acquainted with the area. She immediately entered the nest under the landmark she had learned. Which was one of the fakes. Of course, after a few seconds, she realized her mistake and she came back out again. But after a short flight to get reoriented...she would again make the same mistake.
