Update 4/8/17
I must say, I am shocked. Last time I checked a week ago, I felt like there were a lot less eggs than there were the last time I checked before that (two weeks ago). Now, checking on my Lasius an hour ago, there is not one egg to be seen (not even my speedy niger group 4 queen), and niger group 1 and 9 now look dead. I don't understand at all what is causing this. The only answer to missing eggs means the queens were eating them, correct? I can't think of anything that is causing hunger or stress to any of my queens. They are fully-claustral, so they don't need food. They are in acceptable temperature conditions (71-74 F), they are in the dark, they are only checked on once a week. Their test tubes have humidity. On top of all this, these species are really easy to keep and usually have great odds.
This is almost laughable that my niger group queens are falling apart, whereas both my umbratus groups are alive as ever.
I gave each niger-group tube a drop of sunburst on some tinfoil, tried taking some vids/pics, closed the pot, and checked on my parasites. This is really strange. Any ideas what the heck could be going on in there that is apparently causing much stress to my queens? Maybe the heat guage I'm using is innacurate and in reality is too hot or something.
Oh, and I have concluded what is causing my tubes to deplete quick. The parasites tubes are full and a lot colder, so I'm pretty sure its the heat that is causing the niger group tubes to do that.
Pics later.
