Moved from Aphids.

So we're only supposed to have Lipaphis pseudobrassicae here in North America, but this is much darker. Looks more like Lipaphis alliariae, which supposedly only occur in Europe on the same plant. Wisconsin is no stranger to new introductions though, first place the Soybean aphid was found back in 2001.
