found in this collecting. The Cutworms and other larvae 
will frequently be taken, so that many specimens to rear in 
breeding cages may be found. Occasionally, also, you will 
be likely to come upon a cocoon or ch^salis. It is worth 
while to indicate on each specimen the date, or in some way 
indicate that it was a hibernating insect, as the stage of 
hibernation will thus be fixed. This is often a matter of 
great economic importance. 
This sort of collecting may be pursued to advantage 
throughout the season,although in summer fewer specimens 
are taken, especially in dry weather. The best time then 
to search the under side of boards is just after a day or two 
of wet weather.
