32 oz. deli cups are great for rearing fruit flies, waxworms, and other feeder insects in. Fabric Vented Insect Cup Lids from Josh's Frogs are perfect for fruit fly cultures, wax moth cultures, and as a top for many deli cups that require ventilation.

These great quality Fabric Vented Insect Cup Lids are suitable for use with most deli cups. We recommend them for our 8 oz. and 16 oz. shipping containers, 32 oz. fruit fly cups, and 16 oz. tadpole cups.

Vented Insect Cup Lids will NOT WORK with clear display deli cups.

This is a 500 Pack of 32 oz. insect cups and 500 fabric vented lids.
