This is in a lily cane that is about 7 feet tall. Just happened to notice the white stuff on the leaves and then the hole. I may just go sit and watch. The hole is a foot up the cane. We have lot's of carpenter bees but I never see them make a home in living plants.

According to this article, yep, it could be a "small carpenter bee"

and this moth article:
"According to Penn State College of Agricultural Sciences, Papaipema nebris is native to North America and produces one generation per year. In its adult stage it's a moth that lays its eggs singly or in groups some time in September and October in dead leaves of grasses and weeds. The eggs overwinter and begin to hatch around mid–May through mid–June. Its larval stage lasts between nine and 12 weeks."

This same thread has been through a long discussion over on the insect and bug id forum. The info you just provided has already been put forward. That moth's range is East of the Rockies. There have been more photos posted and stem damage from grazing is visible which is a no to Carpenter Bees. Thank you though for your input. At this point I'm waiting to see if there are any ill effects to the lily.
