This year I thought I’d finish 2021 with something different, an A-to-Z 26-day countdown to the end of the year. So, first up, A is for aphids, a family I intend to look closer at in the coming year. Many species look very similar to each other and so are hard to identify, like these.

But there are other species that are specific to particular plants, like the one shown below. Though my finds haven’t yet been confirmed, from their relatively large size, the fact that I’ve found them twice now on Grey willow, and their markings and the distinctive horny bumps on their rear ends, I’m fairly sure these are Giant willow aphids (Tuberolachnus salignus).
