Jochen Moehr writes from Metchosin: Tonight we have another congregation of six winter moths here. I am amazed by their variability. Jeremy Tatum writes: Yes, this is another challenging case where the variation within a species seems to be at least as great as the variation between species. The first of Jochen’s photographs below is surely Operophtera brumata. I don’t think bruceata is ever quite as plain as this.

The next one is more strongly patterned, so one must consider that it might be bruceata, but I don’t think it is. I think it is probably O. brumata.

I believe the one below is a genuine native O. bruceata. I hope I’m right, but I’m going to stick my neck out and omit the word “probably” in the label!
