With nurseries, or other plant sellers, they're going to be either seasonal or sell plants that can actually grow in the area. I've had to go online to find oleander, ailanthus, evergreen oak and pepper tree. You probably already know to beware of pesticides with nursery stock. A little off topic, but I did get rid of the scale insects on my pepper tree by cutting off every branch with leaves and leaving only the tiny buds, set things back a bit, but it worked. Oleander and peppertree? You should come down to California—they line freeways with that stuff. |

Can anyone show us a comparison photo of P. clodius and P. smintheus together ? is a link to the only photo I found. It has a copyright watermark but it is otherwise useful. In the wild the two can be differentiated by the antennae color; s mintheus has white/black segments while clodius has all black. The hyaline regions of the FWs on clodius are usually much larger, and there are no red spots on it's forewings, which are common (but not always present) in smintheus. In clodius, the black "bands" in the forewing discal cells are more bandlike, while smintheus has rounder "splotches". |

Thank you very much Crake for that informative link differentiating the two species apart. I appreciate the time spent looking it up.
Thank you as well mikeh for the wonderful picture of your personal captures.

Hi all, here’s a quick update:
I pulled 2 Parnassius clodius eggs out of the fridge yesterday and they emerged this evening. I placed a Fumaria capreolata leaf with them and they immediately started eating it. Hopefully, they’ll stick with it for the rest of their development; I now would suggest trying Fumaria as an alternative host to dicentra.

Good luck, please let us know what happens.
Adam.

Good point, anything form Home Depot or Lowes will be heavily treated with Neonics and often have a little tag saying they have been treated, but those tags easily fall out. |

Good luck, please let us know what happens. Adam. So far, so good. Both larvae have been eating consistently and one has entered apolysis. They're also very energetic; they move almost twice as fast as other caterpillars. I find it interesting that they took so well to capreolata, considering it is non-native and that some populations of clodius seem partial to their respective Dicentra hosts. For example, in Logan Crees and Diane Debinski Dr "Natural History Observations on Parnassius clodius altaurus and Parnassius smintheus magnus (Papilionidae) in Grand Teton National Park, Wy," The Journal of the Lepidopterists' Society 75(1), 70-74, (9 April 2021), they found that yellowstone WY populations of P. c. altaurus (which feed on D. uniflora) mostly refused to feed on D. formosa. |

Major update: Both larvae escaped their enclosure, walked on duct tape, and died. Otherwise, they were doing very well. I’ll let you know what happens with the next batch.

One time I used some tape with some larva, for a reason I forget now, it took the larva only a matter of hours to find the sticky
material and there they stayed.
If it's a hole in an enclosure, an improperly tied sleeve, or a way to drown themselves- live and learn.

Hi all. At Adam's request I'll give a quick update on the situation.
I only had 2 larvae emerge due to a limited supply, one escaped and died; I kept the remaining larva under 72-79 degrees F for 3 weeks. It fed regularly on the *Fumaria* and made it all the way to the fourth instar before failing ecdysis.
1 larva is certainly not enough data to draw conclusions from, but it was rather small during development so I wouldn't bet on *Fumaria* to yeild consistent results. When I get some more eggs in the summer I'll try again.
