hehe ,so Kiam ,I can do it for you ,but what is you price? ,with posting and more it is very cheap like antstore ,the best is ,when you make it on your own.
heh I aint good at designing things like that:P Myrmica rubra can swim very good I had alot of colonies and i mean alot in my last few houses you couldnt walk anywhere without them around Im pretty use to there bites now which is good
Something that made me madder is when the flight thing happened I thought it was a war because when you went around they just flew on you and they were on paths and everywhere and it looked like fighting :S
For Myrmica is the best only ytong nest ,sometimes you can use glass tube ,but ytong is better. It must be wet ,because when it is dry ,ants will to dead very quickly. Myrimca like wet climate. It is all what I can tell about formicarium for Myrmica.
