LOCATION: Steve M. Spomer located female 1003 North 52nd, Lincoln, Lancaser County, Nebraska on host plant Antennaria parvifolia - Small leaf Pussytoes
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.
Larva: #1 was a larva for 27 days.
Larvae varied a great deal with some being 3rd, 4th or 5th Instars at the same time
First Instar - 22 May 2012
Second Instar - 27 May 2012
Third Instar - 31 May 2012 - 4 mm
Fourth Instar - 4 June 2012
Fifth Instar - 8 June 2012, photo on 9th 20mm long
Fifth Instars - 16 June 2012 - 45 mm long
Pupa: Pupae stage was about eight days . Pupae were about 21 to 24 mm long. Some larvae had a bad reaction to a batch of host plant and became sick showing watery frass but eventually recovered on different plants. Those pupae were smaller as were the adults. #1 and #2 formed a pupae on 18 June 2012 and emerged 26 June 2012
Hibernation: Overwinters as ?
Specimen: Pinned by Jacque Wolfe
Oviposited on Antennaria parvifolia
Fed on Circium undulatum - Wavy-leaf Thistle
