Insects
Dean's table gives an empty worker honey bee an average airspeed of 18.6 mph (8.3 m/s), tethered, from Hansson 1945. A laden worker on the same method is 16.1 mph (7.2 m/s).

Dean, Table 1. Apis mellifera worker, empty: 18.6 mph (8.3 m/s), average, airspeed, tethered, Hansson 1945. The laden worker on the same method is 16.1 mph (7.2 m/s) and is not a separate record. Ground-speed cells for workers, including 12.4 mph (5.56 m/s) and 13.7 mph (6.12 m/s), are not this row. The figure is 18.6 mph (8.3 m/s).
In context
Worked out from the sourced figure above, which stays the ranked number.
Quick answers
A western honey bee can travel 18.6 mph (8.3 m/s), a verified measurement.
Western honey bee is labeled Verified. Independently measured and published, for example in a peer-reviewed study or with certified timing.
The figure cites University of Florida, Department of Entomology and Nematology, “Book of Insect Records, Chapter 1, empty honey bee.”
Western honey bee is 4th of 10 on Fastest Insects.
Mechanism
An empty worker honey bee is ranked at 18.6 mph (8.3 m/s) airspeed, tethered, from Hansson 1945 as Dean reprints it. At his key of about 2.2 mph per m/s, that is about 18 mph. A laden worker on the same method is 16.1 mph (7.2 m/s).
The cell is coded A / A / T: average airspeed, tethered. The insect is held, so the number is not speed over the ground and not a tailwind. Ground-speed cells for workers, 12.4 mph (5.56 m/s) and 13.7 mph (6.12 m/s), are a different quantity and are not the figure.
Dean’s next cell is a full worker at 16.1 mph (7.2 m/s), still Hansson 1945, still tethered. Carrying nectar is slower on that method. The empty worker is the one that counts because it is the faster of the two tethered airspeeds.

Ground-speed cells for workers, including 12.4 mph (5.56 m/s) and 13.7 mph (6.12 m/s), are not this row. The figure is 18.6 mph (8.3 m/s).
Tethered airspeed. The full worker is 16.1 mph (7.2 m/s) on the same method. Ground-speed rows are not substituted.
Reference
Context
Dean’s Table 1 lists an empty worker of the western honey bee, Apis mellifera, at 18.6 mph (8.3 m/s). The codes are average, airspeed, tethered, and the citation is Hansson 1945. A tethered measurement holds the insect in place and reads airspeed, which is why this cell is ranked and a ground-speed cell is not. The figure is 18.6 mph (8.3 m/s), qualifier verified.
The same table gives a full worker 16.1 mph (7.2 m/s) on the same tethered method. Carrying a load is a slower cell, not a second entry. Other honey-bee rows in the table are ground speeds, including 12.4 mph (5.56 m/s) and 13.7 mph (6.12 m/s). Those are a different quantity.
