The male was most likely eaten by the workers as a protein supplement for the larvae. Usually "naked" pupae of Camponotus sp. will be eaten. Also, about your heater, it may be too hot for them. Remember that most ant nests are underground, and are heated at one portion (the upper levels) and are cooler (MUCH cooler) deeper in the earth. It may be too hot. What is the voltage to your heater/temperature?
Ive tried all differet ways to heat these since last november when they seemed to become pretty dormant but thinking about it this all happened after i moved their nest inside the arena, they did seem to enjoy the plastic tube leaving the nest so perhaps i should revert back, i also used to have the nest in a bowl of water but now i water the nest from above. I suppose its a bit of a no brainer really,,,go back to the old way when they were happy.
Thye heat pad im using is back on the rear again its only a small 10 watt.
Keep it simple :)
Cheers
I can only think that your new method isn't keeping them moist enough. Try adding water more frequently, I did this with my Messor e rectus as the queen had stopped laying and and the larvae went dormant. After increasing the water frequency to the nest, the larvae started growing again. Worth a try.
Gonna try and get them back how they were before at the weekend, thx Bugsy.
I'm gonna keep this thread going because there is so very little information out there about this species, so if anyone has a colony please feel free to ad to this.
So i have put the colony mostly back to how i started with the y-tong nest and a tube leading out to a small plastic arena with a couple of cm's of soil in the bottom which is kept damp. The nest sits in a shallow water bowl with a small 7 watt heat pad under one corner. I know these ants will feed from the honey water but actually catching them in the act has been quite rare but looking at their gasters they are obviously feeding on something. The small flies, crickets, roaches, mealworms all seem to be ignored but there is life and movement in the nest. There are a few pupae now which have to be fron the larvae from last year as there hasnt been any other larvae present that the pupae could have been from. This brood must be at least 7 months old?????
So at last things seem to be working but something is missing as these ants were so much more active when i first had them.
So nest temp about 70f- 75f and humidity high.

A pupae is about to hatch, i hope its a worker...and there is another pile of eggs..
How is your colony doing now?
