D 38 Ugly-nest Caterpillar, Archips cerasivoranus (Fitch) Lightly infested clumps of choke-cherry, mainly along roadsides and lakeshores, were observed at many locations in the district. Occasional colonies occurred on pin-cherry and willow at widely scattered points. Population levels increased slightly at sample locations (Table 5).

Several pockets of light infestation occurred in parts of Burrows, Kelvin, Kemp, and Maid townships. Scattered groups of white birch were lightly infested at a few locations in the northeastern part of Cabot and Togo townships. Occasional colonies were observed in Ivanhoe and Pinogami townships near the shore of Ivanhoe Lake in Division 68. Birch Skeletonizer, Bucculatrix canadensisella Chamb. Infestations declined generally to light intensity in 1965. However, moderate to severe defoliation occurred on small pockets of white birch at numerous locations in Kenogaming, Lemoine, Montcalm, and Silk townships in Division 68, and in Groves, Natal, and Togo townships in Division 72 (see map). Light to moderate skeletonizing of the foliage of occasional clumps of alder, hazel, and yellow birch occurred at points where white birch was heavily infested (Table 6).
