These are best used for fruit flies that are kept in a dry climate. The tiny pin holes in the lid help keep your culture from drying out in dry environment. If you have a more humid environment you may like to use our Fabric Waffle Lid. Both work very well on the Fabri-Kal Pro-Kal deli cups size 6-32oz. *Cups Sold Separately*
