I recently went ant hunting and opened up a few small pine cones. The cones were all on the smaller side and had not opened to release their seeds before falling. They were slightly decayed as they were under a layer of leaf litter and pine needles in a fairly shaded and moist area. All had chambers and tunnels in them from previous occupants, perhaps termites and beetles.
I immediately discovered two colonies of Crematogaster minutissima in two separate pine cones, which was awesome since I had never discovered this species. Each colony had two queens, and both had over fifty workers, though I didn't collect every specimen to count them. One colony shared their home with a new Pheidole moerens colony and the other shared theirs with a few Ponera pennsylvanica.
I went on to collect a small bag full of pine cones and had fun collecting several different species inside them, including Aphaenogaster, Strumigenys, Hypoponera, and Nylanderia.
Anyway, my main question was concerning the Crematogaster minutissima. Does this species inhabit most of the Eastern US? I was just wondering how common it is to find them.
