Papaipema nigris was an omission on my part since I failed to check Leslieray's location, although in my defence I'd add that I did say it may not be the only borer to attack Lilium
I had seen an article that suggested P. nigris had been noted in British Columbia but also that that might have been a mis-identification.
Janet, I haven't checked any other references for it but the second link above for Agasphaerops nigra indicates it attacks the bulbs and underground stems whereas this seems to be higher up. Frass was white though on the extension.org page that incriminated it, although it could be for some kind of Noctuid moth also so that probably doesn't help.
