Ailanthus Webworm Moth (Atteva aurea)
Bald Eagle (Haliaeetus leucocephalus)
We had some out of town guest this weekend but they were here mostly to do the D.C. tourist thing. Late this morning the headed downtown to hit the museums and Cathy and I decided to go to the C&O Canal, walking northwest from Pennyfield Lock. It was a beautiful day, warmer than I prefer but only by a little. In the shade and particularly when there was a breeze it was lovely. We saw lots of painted turtles (Chrysemys picta), a great blue heron (Ardea herodias) and quite a few wildflowers. For today’s post I’m putting up two photos. The first is an ailanthus webworm moth (Atteva aurea) on a sunflower (Helianthus) of some sort. The larvae live in communal webs on their host trees. Interestingly, while they are thought to be native to South Florida, the ailanthus for which they are named (Ailanthus altissima, Tree of Heaven), is native to Northern China. It is believed that their original larval host was the paradise tree (Simarouba glauca) and Simarouba amara. It started moving north around the 1850s when introduced Ailanthus altissima contacted the moth’s native range.
The second photo is, as you have probably surmised, a Bald Eagle (Haliaeetus leucocephalus). Cathy had walked a little further along and I waited in the shade at a pretty spot to take a few photos of the wildflowers there. While I was waiting for her to return I looked up and saw the eagle. I was able to point him out to a few others walking or biking on the canal but it was gone before Cathy returned. This isn’t the sharpest photo but it’s pretty clear what it is. The dark spot in the lower right is another bird. There were quite a few, flying fairly high in the sky.
