Here's a hot tip

Early beekeeping journals are full of examples of observations that were ahead of
their time. Sedding (1912) noted that ordinary playing cards could be used to mark
queen nuclei; he reported that queens never failed to return to their own hive after
their mating flights if the hives were properly identified. Unfortunately, the editor
of the journal did not share Sedding's belief that bees (at any rate queens) possessed
the ability to perceive and distinguish forms, and he discredited the notion.
