A comparison of the number of flower choices, decision speed, and learning performance of queens and workers.

* The queen in colony 5 produced only 6 workers and has therefore been excluded from our analysis.† Queen made no errors so has LPI = zero.Data shown are the percentage of blue flower choices made by queens and workers from each colony prior to making their first probe on a yellow flower, the total number of flower choices made, the time taken to feed from a (yellow) rewarding flower (decision speed), and the Learning Performance Index (LPI). Worker data are presented as colony mean (± SE) values.
