We have (In Vermont at least) those huge mosquito looking bugs referred o as "sewing needles", and when I was little one would get into my room or my tent while camping and my mother would say "They'll sew your eyes shut unless you close them." So she'd get me to go to sleep that way, but I believed it to be true.
