SPRING BROOD OF MOTHS. 
At Fort Collins moths have been captured out of doors as early as 
April 26, long before apple trees were in bloom. Ourearliest records 
for other portions of the State are as follows: Grand Junction, May 7; 
Canon City, May 5; Rockyford, May 10. 
Moths from larve brought into the laboratory during April and 
May have continued to appear in good- numbers to June at Fort 
Collins, and moths have continued to appear in cellar breeding cages 
to July 2 The early larve and pupe taken at Grand Junction by 
Mr. Silmon Smith continued to give moths till June 1, those taken 
at Canon City by Dr. Peare gave moths till June 24, and those taken 
at Rockyford by Mr. H. H. Griffin emerged till June 8. In none of 
these cases was any special attempt made to get the latest appearing 
moths for the locality. The extreme range in time of appearance of 
the first brood moths in our cages at Fort Collins in 1900 was 69 days. 
The following table, giving the dates at which the codling moth 
appears in its different stages in different parts of Colorado and in 
some other States, may be of interest for comparison, although there 
are many blanks that can not be filled at present:
