L.S., 
 
This years observation is the same as last year and 2 years ago. In May/June I start seeing smaller workers among larger workers. The difference is pretty striking, smaller workers are 20% maybe to 30% smaller than large workers.  These smaller workers seem to function normally and they have no deformities for the eye. 
 
Again I am wondering what I am looking at. Influence of a pathogen? Influence of nutrition? Normal seasonal change in bee size? 
 
My bees are thriving this year, we had a warm spring. All colonies are on natural comb that has quite some variation in cell size.  
 
I can't find publications on this subject. Does anyone know any?
 
Does anyone see the same in their bees?
 
all the best,
Lennard
