Sorry for what may be a noob question. But my Tetramorium sp E are burying and sealing themselves into a corner of their formicarium. The colony is small: queen and 5 workers plus brood. I brushed the sand aside and within a day they had rebuilt their shelter. Is this a sign they need to hibernate? I was going to put them in a wine cooler Nov 1. Shall I do so now? Pics below. Thanks!
