This summer I had to give away all of my ants when I was going to India because I could not find somebody
to look after properly. Now I keep only two colony's of Tetramorium caespitum : They are easy ants for somebody to look after when I am not there and can feed for a few days on seeds only before been given insects again. They are very interesting too .There is also a controvetial point: The online store site indicate the necessity for T.c. to hibernate , other sites are telling that hibernation is optional not necessary . In fact both can be right, genetic studies make scientist think that MAYBE T.c. is a group composed of different species or variety physically indistinct (cryptic species) but having differences in behavior . Invasive Tetramorium caespitum in NorthAmerica is now provisionally call Tetramorium specie E.
As I like to observe my ants all the year (I myself do'nt enter into hibernation

) I 'll keep my colony's
active all the year . I try and we see if it does work . The room temperature is between 20°c at night and 22°c
(max. 24°c) during the day. The plaster nest is warmed full time by a reptile warming stone and the other by a defective warming matte warming the nest just 2°c above the room temperature . The water tank is under the nest so instead of drying the nest it increase the humidity level .
