Magnified with binocular dissecting microscope. Two small circles are slit sensilla for locating epigastric furrow region. Circled is a visible uterus externis. Female. Specimen was spread after soaking in mild, dilute dish soap. Detail became clearer after drying.

      Left slit sensilla is on lower left portion of circle. I annotated on the phone, thus the crude circles.

      Forgot to mention, this is the 0.5" specimen from previous pic

      Wow this is really nice. It makes me want to save my Avic molts now. I've always waited till they were about 3-4". I think I will try when smaller now. Granted I only have a digital scope.

      Yes. Don't throw them out if you can't see clearly at first. I thought I could see the uterus externus, but when it dried it really popped out.

      @Siderum Thanks for that tip! I have been imaging exoskeleton's that were wet more or less. They reflect too much light at times. However it didn't occur to me to let them dry. I was concerned they would get hard again, and crack up.
