LARCH 
LARCH CASS EEARER ( Coleophora laricella Hbn.) 
J. V. Schaffner, jr. (June 17): Observations made and reports 
received from various sources during May and June indicate a 
general infestation wherever larch occurs in New England. 
C. R. Phipps (June 25): '.This pest was very abundant during the 
season of 1931 with the result that most of the larch trees in 
the State were turned brown in June. This condition is being 
repeated this season although some of the browning has been 
occasioned by late frosts. 
H. L. Bailey (June 25): The .larch case bearer appears to 
have been more abundant than ever before throughout all parts 
of the State. A high percentage of the native larch trees were 
almost completely defoliated. New foliage was starting on many 
New York 
R. D. Glasgow (June 14): The larch case bearer is very abun- 
dant throughout eastern and northern New York. Adults were ob- 
served in Westchester County on the 8th, and in -"Warren County 
on the 12th. In northern New '.York this insect appears to have 
become active as soon as the buds opened, the foliage through- 
out large areas having been destroyed before it had attained any 
considerable length. A very large proportion of the tamarack 
in northeastern New York is now entirely brown. This' insect has 
caused serious and progressively increasing damage to larch in 
northern New York during the past 5 years. Many tamarack trees 
have already died as a result of repeated defoliation by this 
insect.
