Book lice are not actually lice. This common, harmless insect can be a nuisance as they thrive is warm, damp environments. As the name suggests, they are often found feeding on the glue of book binding but also feed on mould and mildew. They also may infest dried, starchy foods that has been exposed to humidity.

    Incredible images. What family is it then, I though they were psocoterans? What an interesting red color near the mouth. Is it from the horse gram or a natural color?

      Yes Sir, They belong to the order psocoptera and family liposcelidae. They are usually secondary pests that cause significant weight and quality loss in stored grain.
      Red colour near the mouth is natural only.
