Palustrine invertebrate populations in the characterization area have not 

 comprehensively been studied. The data in this table (Reinecke 1977) is 

 based on collections made from beaver ponds in central (noncoastal) Maine. 

 At the time this appendix was being prepared, D. M. Cameron Jr. (York 

 University, Toronto, Canada) was compiling a checklist of insects 

 occurring in a scrub/shrub peat bog in central Maine. It is scheduled for 

 publication in 1980. The insect species occurring in emergent wetland and 

 forested wetland are predominantly those which also occur in the upland 

 terrestrial environment ( personal communication from J. B. Diamond, 

 Department of Entomology, University of Maine, Orono, ME, March 1979). 

 Cummins 1973 and Pennak 1953. Many of these invertebrates go through a 

 series of instars or larval stages, and their feeding strategies may 

 change in the process. Unless otherwise noted, these designations are 

 characteristic of the adult organism. C = carnivore; D = detritivore; 

 H = herbivore; = omnivore , P = parasite, and S = scavenger.
