I found reference to a book written in 1996 "Ted Miller's Earthquake Prediction Handbook" claiming that:
"Bees have been seen evacuating their hive in a panic, minutes before an earthquake, and then not returning until fifteen minutes after the quake ended. Even creatures such as millipedes, leeches, squid, and ants have been reported to exhibit abnormal behavior prior to earthquakes."http://users.lycaeum.org/~maverick/quake.htm
There is also an article on the Caltech website that mentions bees swarming before an earthquake:
"For many organisms, behavioral action taken prior to an earthquake could reduce mortality: fish and cetaceans leaving coastal zones, rodents
exiting from collapsible burrows or dwellings, bees swarming, parents delaying egg-laying, etc."
