By far our favorite new springtail for isopod bins. These are a smaller species, about half the size of temperate isopods. They reproduce well, and they are not crazy running around all of the isopods like the tropicals most people use. Upon magnification they are iridescent. You will not regret adding some 24K to your isopod bin or vivarium. This is an 8oz. culture on coco fiber with over 100 springtails. Very limited quantities available.
IF YOU HAVE STRUGGLED TO KEEP SPRINGTAIL CULTURES GOING, THIS IS AN EASY TO KEEP SPECIES THAT DOESN'T DIE OFF LIKE TEMPERATE OR TROPICAL.
These springtails are also very easy to feed out to small animals from the 8oz deli cup. If you keep the cup full of substrate, the springtails crawl on the lid, and if you remove the lid carefully, there will be many springtails on the lid that can be just tapped off to feed small animals.
There are several magnified images that can be found online (not my photos) that show the coloring and iridescence.
