Fall axd Wintkk Stoxeflies 359 Habits of Adults Feeding Smith (1!)10) in his classical report of the "Insects of New Jersey," stated that adult stoneflies "do no feeding upon living plants as far as ; and Rousseau (1931) in his extensive work on the aquatic lar- vae and nymphs of Europe said that the stonefly adult "ne prend pas de nourriture car sa bouche est ; It has been discovered, how- ever, by Newcomer (1918) that several western species of Taciiionema (jiigripciniis Banks, pallida Banks and pacifica Banks) feed upon the buds and leaves of plants and that one species in particular, pacifica Banks, sometimes causes serious injury to apricot and peach orchards in Wash- ington. Wu (1923) has found, too, that some adults of Ncmoura valli- citlaria Wu will feed a little upon parts of the young leaves of the touch-me- not (Ijiipaficns). In view of the general belief that adults of stoneflies which feed are the exception to the rule, it was with con- siderable interest that I found all of the fall and winter species of the Oak- wood area to be feeding. My first in- timation of this fact came about in an unusual manner. On March 5, 1927, some live adults of Tacnioptcryx nivalis were collected at Oakwood and Ijrought to the laboratory at Urbana for further observations. Several days later, much to my amazement, I saw the sole remaining live specimen playing the role of a cannibal and feed- ing upon a dead specimen of its fellow species. After this a careful watch was kept for adults feeding under nat- ural conditions. On my next trip to Oakwood. Fig. 9.

The majority of these specimens were males and females of T. nivalis and A graniilat
