What you probably have

These are the species the name may stand for. The order and the words show how sure we are.

  • Likely

    Entomobrya atrocincta

    Sold as the hobby culture Dimorphic

    The seller lists Entomobrya atrocincta as the Dimorphic Springtail and says it has not been sold under another name. Anecdotal 1

  • Possible

    Entomobrya multifasciata

    Sold as the hobby culture Little Tiger

    The female of Entomobrya atrocincta looks almost the same as E. multifasciata, so animals of the two cultures can be confused. Anecdotal 2

How to tell them apart

The two species are separated under a microscope with a table of setae characters. Variation in the setae of E. atrocincta hides most of the differences. Anecdotal 2

If you sell or buy under this name

Tip Sell stock under a species name only after a microscope has confirmed it, and buy from sellers who can trace the stock back to a microscope identification. Anecdotal 1
