MacLean 1967 Journal [12 August] count the tanglefoot boards. If we use established transects with the habitats already characterized we can do enough to get a good idea of actual tipulid density. Repeat several times, hopefully at low, intermediate, and high tipulid densities. 2 - Use Emergence traps as enclosures. Have more built - and place 1/2 out as soon as desired areas are free of snow, then the remaining 1/2 in comparable locations on the day that the first adult tipulid is seen. The difference between the two sets should represent larvae saved from predation by exclusion of shorebirds. (But only if larval competition is not limiting. If two sets → = numbers, we must conclude that shorebirds are not influencing number of adult insects which emerge.) It's worth a try. Next processed yesterday's bird kill, then drove out to Shooting Station to think about sampling larvae in coastal ponds. Pond margins consist of about 1 to 4 cm. of organic muck lying over gravel. Larvae are confined
