thanks for your detailed response! just as a postscript/update: the barge from south africa was carrying a large crane or other heavy machinery in which the hive had situated itself out of sight and reach (they had to tent the entire thing to exterminate); venezuela does have africanized bees, and coincidentally two weeks later an african bee find at another florida port which had been loaded at the port of la guaira (where the durban barge had also stopped) consisted of apparent swarm remnants (queenless) whose individuals sampled had a remarkable similarity to the original find (queenright)...these bees had an extra forewing flap rarely seen or previously reported, as well as a unique marking on the thorax (dorsal posterior mesothorax). we are awaiting further id test results, including possible dna analysis...will bee in touch when we know more!
