52nd, Lincoln, Lancaser County, Nebraska on host plant Antennaria parvifolia - Small leaf

PHOTOS: Two ova received 18 May 2012
One ovum hatched and was set on host plant Circium undulatum - Wavyleaf
Thistle, then on Urtica dioica
- Stinging Nettle, then on Alcea rosea - Hollyhock but these larvae refused them all.
Received three
other
larvae which had first been set on Alcea
rosea and on which many had died on ( maybe poison
spray). The survivors were taken off the rosea and set on Circium undulatum which they
accepted as a host plant by feeding and making individual silk
nests.
