Using forceps, gently spread the valvae and place the genitalia under a small piece of glass (a broken microscope slide will work). The ethanol dehydrates and stiffens the genitalia so that it retains this position when placed on the microscope slide. Some taxa may be easy to position; others may be very difficult. It is important to work quickly as the genitalia will begin to stiffen in a short period of time.     Tortricids of Agricultural Importance by Todd M. Gilligan and Marc E.
