No, it's not, but have you wondered why they do it? Speculation (unproven  
AFAIK) is that the antennae, being important and sensitive scent detectors need  
to be cleaned of the adhering scents of the smelly interior of the hive to 
help  them operate more effectively in the more rarified scent evnironment  
outside.  Anthropomorphising, they are cleaning their palates.
