The Butterfly Scales are a practical tool for any gardener concerned about the wellbeing of his winged companions. The scales are assembled of fine brass rods. Due to their filigree construction, measurements can only be taken in calm weather.
The long pointy needle carries a test tube at its rear end, which always swivels into an upright position. Therein, a blossom (preferably lilac) is to be placed in order to attract the butterflies. The needle softly deflects and announces the animal's weight.
