Bagworm city

Ever since I came upon a bagworm moth caterpillar (family Psychidae) hanging from a tree back in July, my eyes have learned to recognize them. Now, I see them rather frequently. A couple of days ago I found a bunch of cases attached to the side and the underside of the iron guardrail along a local street.

Each bag was 15-18 mm long and constructed of pieces of grass blades. I suspect these caterpillars, which are now pupating inside their cases, eat grass. I brought a couple of them home hoping that the moths will soon come out and I will photograph and perhaps identify them.
