You´ve all seem to jump on that hedious fungus theory. Is it possible that just dirt/loam/sand got stuck to them?
Just tryin to be a bit optimistic here. :wink:
In case it is fungus take all necessary precautions.
Hoping for the best.
Everything's been said now, but i wanna add two things: @ MrNixy: How can you know that the fungus doesn't transfer via air ??? As Mr. Buschinger said, the transfering ways of the fungus is unknown!
Secondly, I don't think your ants will make it. the longer you let this invected workers in the arena, the more will other ants infect themselves and I think if you let this happen for a while, its sure that your colony will die.
And at least: @ mpir: Yeah, we just jumped on that theory... Do you know anything about this fungus? Can you be sure just of this pictures it isnt a fungus? No, damned you can't !
If it would be dirt or stuff the workers would clean themselves untill all dirt is away. But if they keep living with this "dirt" and even try to clean themselves but don't get it away you cann be assured that it isn't just dirt.
@ Krümel: Because I have cultivated the fungus.

I don't think we should be optimistic that it might be because human error could be on both sides. If this were to get out then it will cause extinctions in areas. It's an alien fungus which they haven't ever seen before.
The queen is dead today. A worker is carrying her for hours all over the formicarium. The remaining workers are seen coming out now.
I will soon wipe the colony out - disinfect it. But here are some more photos. Is in original 8 MP. Picture quality may not be as good as you want, as I took the picture without opening the formicarium. In fact my formicarium set up is always with closed lid with some air holes. I do not prefer the open type. So I guess, the contamination, if any have been kept to a minimum.
The question is, even if I have not boiled the insect, I am still curious how these fungi can appear? So far all the insects I have given are those of local origin, that is, somehow get into my house from outside. I just zap them and introduce directly to my ant. If they carry the infectious spores, surely the lacius niger around my garden will get the same infection as well.
Ditto photoes. Sorry, they are not in original 8MP. I have to rescale to fit the quota allowed for upload the file.
hmm, okay. I think it's difficult to tell if the fungus is the one which is found in Spain. It's most likely, because the ants come from there and the fungus was spotted there too.
Otherwise it might be a fungus you became through feeding. The insects carried the spores and your ants weren't used to it (so Lasius niger in UK have no problems with a common fungus) That might be possible ... I don't know the fungus in UK and which of them might be dangerous for this specific Ant species.
Antstore is controlling their ants they say ... but I don't think they can exclude the possibility that this might happen. Spores you won't see so easy and there's mostly an incubation time before the fungus will start to grow. Nothing is 100% even if you give your best
Without telling which fungus that is, it is difficult to tell who's to "blame" for. As long that is the only case of a fungus infection nobody can tell with just photos.
I'm sorry for you colony, next time it will surely work fine. I'm sure!
greetings
... or maybe it isn't a fungus. it might be moist ... spanish ants aren't used to British rainy weather :D okay, i did't want to joke ... just a little gallows humour
I just found an example of a fungus infection on bullet ants. It's a nice video.

I think I have like some bits off fungus in my lasius niger colony but its not harming them or whatever it is lol
Sorry to hear about your queen, better luck next time.
I'm guessing it is a type of fungus, but it difficult to say, if you want to be sure what it is, you need to put one dead ant in a tube and send it to a laboratory, if you now someone who has one and would like to take a look at it.
