Haycock Mountain, Bucks Co, PA.
Found on Ageratina altissima.
ID courtesy of Martin Hauser:
2-3 koalas bellowing, lots of fresh scats and scent.
Mother with ducklings.
this one has lid on its back. interesting. :)
I found around ten of them.
1/500 shutter speed wasn't enough to "stop action".
Have observed these several times, usually at dusk.
