188.8.131.52. Marking type
Queens can be marked with a variety of paints or equipped with numbered and coloured Opalith discs on top of the thorax (Fig. 2).
- Queen marking pens are handy and make queen marking easier (no risk of spilling the bottle with paint or glue), but usually wear off very quickly.
- Fast drying nail varnishes are also good markers.
- Model car paint can be used.
- The longest lasting queen marker is made by mixing a pigment with shellac.
- Opalith discs (Fig. 2) are commercially available in a variety of colours.
- A special glue is
provided with the discs but partially dried shellac or cyanoacrylate ester
glues (e.g. Super Glue®) will serve the same purpose.
