OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR THE MONTH OF MAY.1925 
This month has been marked "by more widespread cutworm injury than any 
similar period during the past four years. Notes on the destruction of large 
patches of pasture and corn in Ohio, Iowa, Missouri and Kansas, and reports of 
serious cutworm damage in northern Michigan, Connecticut, Indiana, Illinois, Idaho, 
and California have "been received. The outbreak of the army cutworm in the Middle 
lest has about terminated, heavy flights of the moths having been observed in 
Texas and pupation of larvae reported from Montana. 
The chinch-bug situation has not materially changed since our last report, 
as is also the case with Hessian fly, with the single exception of Kansas where 
thousands o<£ acres of wheat have been plowed under on account of the heavy infes- 
tation. 
Flights of the armyworm moths have been observed in Indiana and Illinois 
during the last week in April. Armyworm damage has already been reported from 
northern Indiana and also northern Illinois. 
Telegraphic conmunication dated May 27 has just been received from Alabama 
that larvae of the cotton worm are abundant near Corpus Christi. A note has also 
been received that on May 23 larvae were abundant in several fields near Browns- 
ville, Texas. This is an unusually early appearance of this insect. In 192U the 
first report was received from the Brownsville region on July 23; in 1923 the 
first report was received on June 3, and in 1922 on August 1. In 1 921, the first 
larvae were observed in Lowndes County, Ala., on August 26. The average date for 
the past three years for the first appearance at Brownsville was July 7. The present 
appearance, \2 days ahead of the average and 10 days ahead of the earliest appear- 
ance of this insect in the past three years, is of decided interest as the early 
appearance of the larvae of this insect is usually indicative of serious damage 
before the bolls are formed. We can also, expect damage later in the season by-.the 
moths attacking fruit in the Northern States. 
The corn rootworm seems to be more troublesome than usual this year' in the 
Southeastern and Gulf Region. 
The pea aphid is reported as attacking alfalfa^and clover over a very broad 
region,.. reports having been received from Connecticut, Michigan, Indiana, Illinois, 
and California. 
The clover -leaf weevil seems to be very decidedly more prevalent this year 
than usual in Indiana, Michigan, and Iowa. It is also reported as causing some, 
damage in Maryland and Kansas. 
Tent caterpillars are again proving very numerous in the New England and 
Middle Atlantic States. A more restricted region of infestation is reported from 
Michigan.
