Just got a small colony yesterday and thought I should start a little journal.
So, tiny colony, fungus size less than a golf ball, less than onehundred ants and one massive queen, she is REALY big!
Only a few dead ants. The heat pack was cold but the ants seem to be recovering from the cold (the queen was falling over herslef the great big clumsy thing
There are some mite like animals but I'm not too worried about them, my Acros have done fine with these bugs.
They are in setup like the one I have the Acros in and being kept at constant 24*C (as opposed to the Acros which are a couple of degrees above room temp, so 16-25*C).
When I put them in the setup they did the typical thing of removing most of the brood (as the garden is too small after the journey to feed new ants), which was a shame as there was a huge soldier pupae.
So far they have just finnished rebuilding the fungus garden and taken a tiny bit of eucalyptus, they don't seem too interested in foraging yet, all in good time.
These ants stridulate but no where near as loudly as Acromyrmex e.g. the 1cm Acro queen will make your fingers vibrate but the 3cm Atta queen you can hardly hear.
They have realy long thin legs compared to Acros and are generaly weaker armored (you can pick up an Acro worker without fear of damaging it, infact you sometimes feel the spines on its back go into your skin first, but Atta workers are slender and fragile so you should avoid picking one up between your fingers). I haven't yet decided which bites harder.
With any luck I won't find out why Atta are harder to keep than Acromyrmex (apart from growth rate)
I'll post some picks this weekend.
