Just to test the way temperature affects the 5th instar, I put those in the refrigerator and today when I looked at them they appeared lifeless. After about 15 minutes back outside in the 90 some degree weather, they were moving like yesterday.
Now I know for myself that they can be stored in the cold, but I don't know for how long. There is probably a shelf limit it you will, but I would assume that is quite some time as they go dormant. Several possibilities now exist for me. They can be used as fishbait at a later time, they can be held until sold, they can be held until warm weather comes back around and sent to someone needing them to seed their area, they can be stored in frig. for a reptile owner who wants to have a large quantity on hand for feed, etc.? Talk about a productive, low cost hobby!!!
