Hi folks Yes, bees have "random" ( To Us) behaviour. I Have certainly no challenge to anyone having observed and reported anecdotal events. After all what one has observed I take that for granted as truth. Why should anyone invent tales for any reason. In My experience : Hornets and Wasps (Yellow Jackets ) Have a definite "SPACE" one should not invade. They are also sensitive to vibrations and become very defensive. Bees exhibit such behavior also , but with different values of both. With them it appears it has to do with race , queen , weather conditions, temperature, ect. I have my grassclippings pile adjacent to the hives to keep the weeds away.The weed eater ( Gas engine) and my riding mower poses no reaction as well. I am not ware of a reaction by my electric chainsaw and the Gas one. So, that's another anecdotal tale and I am left scratching my head. Oh, yes, sometimes I get stung when I hug them too much. catfish
