To attempt to define the "habitat" that each species "prefers" and to what extent "other" habitats may be used in conjunction with or both other species. 3. To determine the "life cycle" of each species, with special reference to timing and number of instars in larvae, egg size, emergence and egg laying in the adults. 4. To construct life tables for each species and determine mortality of each stage of the life cycle, if possible. Much more will be said about this later. 1300 Steve and I decided to walk through the drum area and on out to Beach Ridge near the micro-met.
