Beaver 1967 Diptera Study 5 19 June (cont.) of insect sampling for his work and mine. The general plan is to: 1. Sample systematically from pupae (pupal) for all size stages of larvae standard size tundra samples) to arrive at an abundance (density figured logically) of each species of Tipulidae in all the habitats found on the tundra. This will be carried out over a number of years. 2. Quantitate the emergence of adult Tipulidae by use of emergence traps. 3. Compare quantitatively the number of all larval, pupal and adults found and emerged in a defined area that has been excluded from utilization by shore birds and other birds and to an area where free access is allowed to all predators. 4. Determine the water stage of each insect. 5. Investigate the relationship of each species to each other as larvae and adults. 20 June 1330 Designed emergence trap for the Diptera and will have 6 made for start.
