Two More Moths

Here are two more moths that came to the porch light recently. The first is one of the largest moths I have seen so far this year. This is a Pearly Underwing (Peridroma saucia) from the family Noctuidae. The distinctive patterns on this moth are rather difficult to see without looking closely. Thanks to Seabrooke for help with identification.

One of the things I really like about noctuids is how cute they look from the side.

The second moth is very small, less than 10 mm long. This is a Bidens Borer Moth (Epiblema otiosana). The name refers to a genus of plants that host the moth's larvae. In addition to Bidens, the caterpillars will feed on ragweed or smartweed. I suspect the latter hosted this moth in its larval stage, as there is quite a lot of smartweed around the house.
