Temperate Springtails (Folsomia candida).
These ship in a deep 8oz culture already producing with offspring and adults. All cultures are shipped via calcium clay. Clay is a superior medium for springtail production and ease of feeding.

These have the added benefit of calcium - bearing clay, so the container can be put inside your animals / frog's enclosure for the added benefit of calcium absorption! These cups also contain very high production.
