Iris gardeners encounter many natural enemies of iris plants, such as leaf spot, soft rot, mold, and bacterial infections, but how much do we know about iris borers?

Interesting phenomena with my Oh Canada. The first bloom of the season the past two years has got stuck and failed to open. Tom said that when the flowers are frozen, that can prevent opening, but our temperature has been above freezing. However, there has been a lot of moisture, rain, that could be causing some issue with the petals failing to separate. I'm asking if anyone else in our community has seen this since I haven't had any issue with any other dwarf iris sticking and ultimately not opening?
