If you visit http://www.okstate.edu/ag/asnr/hortla/ftpcns/ofm.htm you can 
see photos of the moth, tree damage and monitoring traps.  Another good 
photo is at 
The key to spraying is the timing.  If you visit 
http://lawnandgarden.unl.edu/scripts/com_disease_insect.cgi?ID=514 you will 
find info for Nebraska although you are in the same Zone 5 as we are so your 
timing is relatively the same as ours and Michigan.  The MSU info at 
http://www.ipm.msu.edu/fruitpests/orientalfruitmoth.htm will give you as 
much info as you might need for timing your sprays.  Hope this helps.
