Koford 100 Cynomya ludorici anus April 29, 1955 Nr. Ft. Collins, Colo. Brief visit to Spring Canyon Dam colony in forenoon. Saw 10 out: 1 near #24, 1 between #49, 1 mm. 16, 150' to W. of it, 2 near #11, 150 yds. S. of these, 1 mm. some 50 yds. W. of #11, 1 mm. #19, 1 mm. #35. April 29, 1955. At 9 a.m. took 2 from traps in wheat field in Fossil Creek, Sec. 4 (S. side of colony). These both small appearing + heliotes walking. Left 7 steel traps between burrows in field there. Mr. Stich told me that area inoculated after planting last (?) year. The wheatfield on N. side col- ony, where most C.L., planted last fall & "blowed out." No C.L. in field 2 years ago, Stich said. He hoped that Mr. Brassey, Lesser, would have the C.L., possessed. Stich said sometime tests dropped into C.L. hole & broke a tire. At 9 a.m. at least 8 on the S. slope in wheatfield at N. side colony, I saw burrows start- ed along streambed (not sure C.L.) going in from rock banks & under sod layer. Saw one C.L. atop slope (20%?) to S. of 5. wheatfield, at yellow earth mound (no second slope?). Many lines 4-5' long when ditched between ridges (3-4" high) have wheat growing. || At CPER overcast & windy 11 a.m., so far out. One yd. 40 yds. E. of E. fence allowed me to approach to distance only 50' before dropping down burrow ridge (Cares) (= within wheatgrass) new-growing green in some low spots, Bouteloua graminea what green, some apparent Muhlenbergia green, Coguelliis (subcut- land, alcyon line) with heads, Eupatorium cuneatum but not flow- ering yet. Many new leaves on closely trapped shrubs. Saw 2 Staphylinid beetles 3/4" long walking over ground away from burrows. Took no Phryganea or colony. Some well drained sections have almost no greenery in grass, dominantly clump
