During the spring of 1933, an adult convergent ladybird beetle, Hippodamia convergens Guerin, was placed in a 3-dram homeopathic vial with a number of nymphs of the potato psyllid, Paratrioza cockerelli (Sulc). The ladybird immediately grabbed a psyllid nymph and began to eat it. Ten fifth-instar psyllid nymphs were eaten by this predaceous beetle during the one and one-half hours that it was caged with the nymphs. It was noted that moving nymphs were taken more quickly than those at rest, but the beetle showed no reluctance at taking the scale-like nymphs which were quietly feeding.
