The insect order Hymenoptera is already noted as including most of the 
eusocial insects such as ants, honeybees, and wasps. Now, 75% of all 
bumble bees tested have been reported to be able to roll a small ball 
around to use as a step stool to reach a food source on the underside of 
a low hanging ledge.
