At Alton Mr. E. Hollister informs me that it was noticed for the 
•st and only time m 1876. On the other hand, Mr. B. Pullen of 
entralia, a well known member of the State Board of Agriculture, 
.ites me in a lecent letter i << The strawberry leaf-roller is not 
)W to us here, but _ it has never been very destructive, and its 
esence m a field this year does not necessarily insure an increased 
imbei next. I have seen more or less of them for ten years past, 
ave known them to be quite numerous in places one year and 
e next so few as scaicely to attract attention. 5 I regret to be 
liged to add that observations and collections made during the 
st summer in Southern Illinois, show that it has extended its 
vages to that section in a way to indicate that it meets there with 
' c ^ 1 J :na ^ lc . c h®ck. It was quite abundant, although not destructive 
a field of Mr. Earle’s, near Anna, in Union county; and in 
^ vas discovered to have seriously damaged a field belonging 
Mr. Condit, at Centralia. It is evident, therefore, that straw- 
rry growers throughout the State are liable to its attacks. 
LIFE HISTORY. 
According to the general account of the species by Walsh and 
ley, “there are two broods of this leaf-roller during the year, and 
3 worms of the first brood, which appear during the month of 
ne, change to the pupa state within the rolled-up leaf, and become 
note reddish brown moths during the fore part of July. After 
iring in the usual manner, the females deposit their eggs on the 
mts, from which eggs in due time hatches a second brood of 
rms. These last come to their growth towards the end of Sep- 
aber, and changing to pupae, pass the winter in that state.” 
Cho species was known to them, however, only from the latitude 
.Northern Illinois. Our very scanty subsequent observations bear- 
■ upon the life history of the species in that region are consistent 
h the account of it given above, except that it has been noticed 
Normal that a considerable number of the moths hibernate, 
rearing on the wing during the first warm days of early spring! 
ese belong, of course, to the second brood. On the 20th of June 
the present year, the larvae were found rather abundant in fields 
it Normal, and several placed in breeding cages commenced to 
erge as moths on the JOth of that month, the last transforma- 
is occurring July 10th. From the brief account of the insect in 
Sixth Report from this office, we learn that living larvae were 
eived by Dr. Thomas, from Tazewell county, in Illinois, on the 
of November, and that his correspondents had noticed them on 
Lr plants as early as the last week in September. 
he data obtained from Southern Illinois during the past sum- 
, by collection and breeding, do not correspond to the current 
3unt of the life history of the species, and indicate the probable 
I | ri ' e uce of another brood, in that latitude. On the first of July, 
! larvae were found abundant in the fields, and a number of speci- 
is sent to the Laboratory on the 9th of that month, were reared 
weeding cages. Pupation was nearly but not quite complete by
