COLLECTING AND REARING TERRESTRIAL AND 

 FRESHWATER INVERTEBRATES 



F. E. Lutz, P. S. Welch, and J. G. Needham 



MUCH that has been stated in the preceding pages by Dr. Galtsoff 

 for marine invertebrates is equally applicable to freshwater forms. 

 It will suffice, therefore, if we merely add some notes and suggestions 

 concerning methods more applicable to inland aquatic, terrestrial, and 

 aerial invertebrates. 



COLLECTING AND HANDLING LIVING SPECIMENS 



For collecting and transporting the larger inland invertebrates (cray- 

 fishes, clams, the larger snails, dragonfly nymphs, diving beetle larvae, 

 etc.), the small seines, traps, bait pails, and live boxes of com-
