Hi, I was just wondering if this mites can harm my culture or not. The mites are brownish white, I don't know how they came, the container I have my culture is totally sealed. Are they harmful to my culture in any way? Thanks in advance. I don't have a great camera, but uploaded this to youtube, you could see the mite there.

Unfortunately that does appear to be a predatory mite, Stratiolaelaps scimitus. Which specialize in eating fungus gnats, other mites, and yes, springtails.

Also, FYI, the "Bilobella brunearae/Protanura sp. Orange" stock in the hobby was more accurately ID'd by an actual springtail taxonomist, they are now ID'd as Yuukianura aphoruroides. 😄

G..damnit, I bought each of these on two separate occasions thinking they were two different species of orange springtails. Thank you for the info!

Aaand one of them has been compromised by predatory mites like above after a gnat infestation, too, so that's good to know I have a backup colony after all...

LOL no worries, there's been a lot of names thrown around haphazardly, all tentative IDs, but now that a taxonomist has actually examined them we know they're Yuukianura aphoruroides finally... I don't know how long it's gonna take for people to stop using the old names for them though. 😂

Well, at least you have two cultures now. 😅 Hopefully the mites don't completely eradicate them from that one cup though.

Do you have the reference of the taxonomist who has examined them? I mentioned this to a local invert breeder and he said yes to Protanura now being ID as Yuukianura aphoruroides and no for the Bilobella brunearae - he said these were still under evaluation but offered no source to back it up... Would you have a link to a publication or something for further reading on this mayhaps? Thanks for the help!

The taxonomist who ID'd them was Frans Janssens.

Thank you! I will try to find the reference for Bilobella. Nothing so far on ResearchGate and such...
I think you misunderstood one of my previous comments... 😅 Bilobella brunearae is still a valid species, it's just that none actually exist in the hobby. All "B.brunearae/Protanura sp. "Orange"" in culture are actually just Yuukianura.

Oh, thank you for clarifying! Are you talking about the hobby in the US or worldwide? I'm in EU and Bilobella braunerae are found in my country, for the matter. I don't have any reason to believe they are anything other but B. braunerae... This is so confusing. 😅

This is the case for the US hobby, and we have yet to see actual Bilobella enter culture in Europe either (if they do it'll probably make the rounds on various Facebook groups as big news for the hobby lol). AFAIK all the stock in the US came from Europe, and only a single source of that species were collected in Europe in the first place. They were initially identified as Bilobella, then Protanura, and now finally Yuukianura.

Interesting!!! Is it that stock advertized as coming from southern spain that I've seen around a few times?
