Zophobas morio. A nutritionally superior live food source for large reptiles and amphibians. They are 2 to 4" L and do not readily change into beetles, as do mealworms. If maintained properly (not too much moisture), their shelf life may be 6 months or more! They are easy to maintain at room temperature (no refrigeration) and can be raised in peat or sawdust in a low, flat container.
