Comb worker cell size measurements
Introduction
The suggestion that bees raised on comb with cells smaller than determined by conventional foundation may be better able to cope with Varroa1 has attracted the interest of apiculturists and apiologists alike. However, a number of experiments reported in peer-reviewed journals have failed to demonstrate any overall advantage of small cell comb based either on small cell (4.9 mm) foundation or made of plastic.2-7 A criticism made of these studies is that they are too short-term, the longest lasting being 13 months,4 whereas anecdotal evidence accumulated over two decades suggests that a combination of withdrawal of acaricides, natural selection and small cell comb needs to be applied for several years before a Varroa resistant population of bees is established.
An alternative approach has been to let bees build natural comb and develop their own preferred cell size range. In a study lasting three years, natural comb was compared with comb based on 5.3 mm cell size foundation regarding the survival, Varroa mite drop and productivity of the respective colonies.8 Perhaps surprisingly, the worker cell size of the natural comb colonies was larger (5.4 mm) than that of the foundation comb colonies (5.3 mm). No decrease in natural cell size was observed over the three years of the study.
If, despite the accumulating evidence to the contrary, small comb cells are essential to the ability of Apis mellifera to co-adapt with Varroa, it would be of particular interest to natural beekeepers if small cells are achievable by allowing colonies to develop on foundationless combs, i.e. by using only starter strips of unembossed beeswax. It is even conceivable that the selective pressure of Varroa could force Apis mellifera gradually to develop a cell size range which is smaller than the range that has been found in its natural comb throughout beekeeping history.
How raising bees in small cells would help them vis-à-vis Varroa is still largely a matter of speculation. One possibility is that the tightness of fit of pupae in cells may increase mite mortality.9 However, as the size of adult bees emerging from small cells is slightly reduced, this too may have as yet undocumented effects on colony health and vitality which enable the bees to resist Varroa.
Searches in the beekeeping literature over the past 340 years for reports on natural cell size show an overall average value of 5.3 mm.10 Authors who have reported worker cell size ranges for comb of bees that were unlikely to have ever been reared on foundation have observed a variety of minima: Cowan 4.72; Maraldi 4.92; Cheshire 5.08 and Root 5.21.10 Both Cowan and Maraldi gave different values in different places in their writings, so there must remain some uncertainty about the validity of their values.10 It is noteworthy that if values as low as 4.7 mm are a common property of natural comb then it differs greatly from the size of foundation. My locally purchased foundation has a cell size of 5.7 mm when measured horizontally, 5.4 mm in the two directions at 60º to the horizontal.
This paper reports measurements on the cell size of natural and near-natural comb in the author's locality (NW Wales) with a view to seeing if sizes below 5.0 mm are commonly encountered or even increase with time elapsed since the colonies concerned were kept on a foundationless system. In the Warré hive, new boxes are nadired (added under the brood nest). This allows successive generations of bees to grow the comb downwards and this may produce a gradually diminishing average cell size and the appearance of an increasing proportion of cells below 5.0 mm.
Methods
Cell size was measured in three different ways. Initially, it was with a good quality millimetre ruler that had been checked against other makes of ruler. After 22 February 2011 digital calipers were used where only a few measurements were required. Where cell size was measured row by row across whole combs measurements were made by photography, digitisation of landmark data and calculation by spreadsheet.
Combs were photographed in good light with a digital camera (Fuji S7000) placed 3 m from the comb and the lens aligned to the centre of the comb. The comb face and camera lens were adjusted to be perpendicular to the line between each. The camera was mounted on a tripod and fitted with cable release. Photos were taken in available light, either sunlight or tungsten filament or a mixture of the two. The diaphragm was stopped to F8 and the digital resolution set to 6 megapixels 'fine', the maximum available for the camera. The lens was set to maximum optical zoom.
Images were transferred to a computer, cropped to retain just the comb area and digitised using F. James Rohlf's 'tpsDig' software.11 Generally ten cells were measured for each row from the bottom to the top near the middle of the comb on both sides. Occasionally combs were curved. Where it was not possible to have ten cells per row orientated perpendicular to the line between comb face and camera, five cells were selected.
In order to calibrate the measuring setup, three plastic bars 50 mm long, measured with digital calipers, were pinned to the comb face. The positions of the ends of the bars and rows of 10 or 5 cells were digitised and saved to a *.tps data file. These data are the x,y coordinates of the points measured in pixels. The data were then imported into a Microsoft Excel spreadsheet, and, using the values for the three calibration bars the cell size calculated with the generation of mean, range and median statistics. The photographic method was verified with digital calipers and found to be in excellent agreement.
The following photo shows part of the landmarked image of a comb face with the three calibration bars pinned to it:

The comb with the smallest cell sizes was in 'Warré 11' box 2, i.e. the second box to be drawn, was first constructed in 2008. However, in the spring build up in 2009, the bees tore it down and reconstructed it. The following photo shows this remodeling in progress.
Variation in cell size with position on comb
The following graph shows how cell size gradually decreases down a comb and possibly increases a little near the top-bars of the next box (the step on the left of the graph). The more erratic nature of the graph for the top of the comb (on the right) is because, during honey extraction, the combs were broken from the top bars at different distances from them, so some combs had fewer data points near the top, thus increasing the scatter. The full comb height is about 195 mm (200 mm minus a bee space). The 38 rows shown here at an median cell size of 5.18 mm account for a comb height of 197 mm, which is satisfactorily close.
Discussion
The smallest cell size detected so far in colonies in this locality is 4.8 mm. In the 25 combs examined so far only a very small number of cells below 4.9 mm in size have been detected. Possible reasons for this include:
- the race of bee;
- insufficient time elapsed for bees formerly reared on foundation derived comb to reduce their body size and thus the size of cells that they build;
- comb spacing in Warrés of 36 mm, i.e. larger than found in natural nests
However, that there is any small cell comb at all raises the question of whether keeping bees on uniformly sized comb derived from foundation compromises, however slightly, certain aspects of colony wellbeing.

It is noteworthy that the smallest cell size was in comb that was remodeled by the colony a year after it was first built. The hive was originally populated with a swarm from a National hive. Possibly the year that had elapsed since hiving had allowed the effect of the large cell comb in the National to wear off.
It is clear from the spreadsheets for row by row cell size measurements (downloadable above) that the smaller cells tend to be in the middle of the comb. This accords with Cowan's observation.12 Larger cells are at the bottom and top, with the largest cells, those that were built for honey storage, being at the top.
This is ongoing work. More data and comments will be added to this page as comb samples become available.
It is interesting to compare these foundationless comb results with the cell size of commercial foundation. My commercial wired brood foundation for the National hive was obtained from C Wynne Jones of Rhuthun, North Wales. Measured horizontally between parallel sides of hexagons the embossed cell size is 5.8 mm. Measured in the other two, near vertical directions it is 5.4 mm. The distortion of the hexagons is clear to visual inspection.

The Cast |
Bee 2.4.11 Song
is an amusing, small-scale comedy with music which successfully throws in everything but the kitchen sink to engage and entertain us.Bee 2.4.11 2017
The student competition is set in a gymnasium at a middle school in Putnam County, New York, where six students (played by adults) and, briefly, three audience members compete to win the right to complete in the 'national' spelling bee.
Most of the six students have broadly drawn, largely unhappy histories which are largely played for laughs, but, eventually, they engage our sympathy and involvement. There is an uncomfortable dichotomy inherent in Rachel Sheinkin's book, between the comically caricatured nerdiness and callowness of the youngsters and the sympathy and respect which such youths deserve. Happily, for this production, director Marc Bruni has toned down the broad comic exaggeration of the Broadway Circle in the Square edition and created a more emotionally satisfying Spelling Bee.
The redoubtable James Lapine, director of the Second Stage production and its Broadway transfer, seemed to have punched the material up, creating a gag-laden, lightweight entertainment. The commercial success of his efforts is undeniable. However, the now well established musical benefits from the somewhat less frenzied touch applied by Bruni. Bruni still employs the aisles and a ramp around the front of the stage to incorporate the Paper Mill auditorium into the gymnasium setting, and his production nicely fills its larger confines.
The entire cast is well up to the task at hand. Will Blum portrays William Barfee (he is disregarded as he informs one and all that his name is pronounced 'Bar-fay') who visualizes how to spell his words by spelling them out in comic dance-like movements with his 'magic foot.' Overweight and suffering a mucus membrane disorder, the hurting Barfee is a boastful and disagreeable nerd. Blum smoothly portrays Barfee's flowering as he responds in kind to the warmth shown him by another contestant, Olive Ostrovsky.
Brandon Yanez nicely captures the comic frustration of Chip Tolentino. A well-adjusted smarty, Chip expects to repeat his victory of the previous year's bee until, aroused by a girl in the audience, he violates a rule while correcting a spelling. His ensuing upset is overcome when he realizes the benefit of his budding manhood. Lyle Colby Mackston smoothly rounds out the trio of boy contestants as Leaf Coneybear, the family underachiever who comes to recognize that he is smart and really belongs in the contest.
Ephie Aardema is on target as the frazzled Logainne Schwartzandgrubenierre, the lisping daughter being raised by her two competitive gay dads who try to lead her to victory by any means possible. The two most interesting contestant roles fall to Olivia Oguma as Marcy Park and Ali Stroker as Olive Ostrovsky. The charming Oguma's Park is the best speller in the contest (she competed strongly in the Nationals last year), but she is depressed by the extreme pressure to succeed in all endeavors to which she is subjected by her extraordinarily demanding parents. Although no mention is made of her ethnicity, it seems implicit that Park is from a stereotypical Asian (Korean?) family, and her situation calls to mind the widely discussed book by Amy ('no play dates') Chua, 'Battle Hymn of the Tiger Mother.' While there will certainly be differing opinions on this issue, it is too facile to snappily depict Park painlessly finding joy and liberation by purposely misspelling a word (the parochial school girl Park receives a visitation from Jesus in which he flippantly gives her the okay to dump the contest). I cannot help but wonder whether author Sheinkin would ever approve of herself or any children in her family doing such a thing.
Ali Stroker is most engaging as the perky, but unhappy, Olive Ostrovsky. Neglected by her self-centered parents (her mother is fulfilling herself in India and her father is too busy to attend the bee). It merits noting that Stroker is confined to a wheelchair because the presence of an actress with a disability portraying Ostrovsky actually enhances Spelling Bee. It ties in well with dialogue relating to a teacher's surprise that she has arrived for the spelling bee alone. Most importantly, it deftly reminds us that children, accomplished children, come with a full range of abilities and disabilities, and makes this production more involving, realistic, involving, all-encompassing and compassionate than it otherwise would be.

The roles of the three adults administering the bee also combine humor and angst. Teacher-host Rona Peretti (Marla Mindelle), Bee Director-Vice-Principal Douglas Patch (David Volin), and ex-convict performing Community Service, Comfort Counselor Mitch Mahoney (Jerold E. Solomon) are each very well played. There are very disturbing aspects to the light treatment and (here is that word again) facile redemption granted to Patch by Sheinkin's book.
It is doubtful as to whether anyone ever exited Spelling Bee humming any tunes from William Finn's slight, serviceable score, but his lyrics well complement Sheinkin's book. Wendy Seyb nicely incorporates Stroker into her pleasant choreography. Anna Louizos' adequate set incorporates space for the small on-stage and, at most times, out of sight orchestra.
While this review provides sufficient information to warn off more conservative parents who might have different standards, Chip Tolentino's 'stiffy' and one or two truly unnecessary swear words notwithstanding, The 25th Annual Putnam County Spelling Bee is a delightful fun show for school children of all ages.
