This time of year we have large bee's putting small dead grasshoppers in the track space above the sliding aluminum storm windows on our porch. The spaces are about 3/8" wide x 5/8" high x 24:" long, the length of the window, stuffed with small dried grass along with some grasshoppers. We see the bee's bringing the grasshoppers but it appears they are storing them as it's not a hive or nest.and don't spend any time there. Are they just storing a food supply for future use? Any information will be greatly appreciated.
