This occurs with the greater number early in July.^ In the warm weather of midsummer the larvse complete their transformations. Fig. yy.

To trap practically all the codling moths in an orchard it is only necessary to scrape all loose bark off from the trees and fasten around the trunks a band of burlap or heavy paper. Remove the bands and collect all larvae once a week during Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hodge, Clifton Fremont, 1859-.
