The second batch of Lasius niger arrived the other day. Don't be fooled by the name – they're just your average UK garden ant. Due to the cold, it's hard to get ants in the 'wild', but fortunately there are mail-order places for this sort of thing.
Here you can see them settling in to their new home, next to a feeder with honey, water and a ramp to the more hospitable sand-filled nesting site. They're particularly slow movers, these chaps, and not very explorative (they've barely touched the honey), but give them a few days and they should be all settled in.
