Approximately 25 Extra Large Butterworms
The butterworm offers more than double the Calcium content of any other feeder insect. Its protein levels are high, compared to those of a cricket or mealworm, and they are very simple to keep.
Keep in the fridge in the vegetable drawer, and ensure they remain dry in sawdust they come in. DO NOT FEED. They will begin to hibernate in the cold temperature. To feed, simply take out as many as needed, and put into a bowl as suggested below.
THESE WORMS CAN LIVE FOR UP TO 4 MONTHS IN A NORMAL FRIDGE
Butterworms are easy to feed to your reptiles (they wont jump around or escape like crickets, hoppers or roaches) simply put them in a vertical sided china bowl (like the ones for hamster food from the pet shop) and the wriggling will attract your reptile's attention.
