There is a good chance that this is the larvae of a fly which may infest the
buds of various iris, particularly those such as siberians, japanese and
species like versicolor and virginica and setosa, and eats the forming bud.
For the most part this damage is not noticeable until the bud fails to open
or opens with a very damaged bloom. A smaller bud than normal is
occasionally symptomatic.
I understand that this problem may be more prevalent in corn growing areas
of the continent.
The problem may be remedied with.......CYGON... which also is used for iris
borer control.
...or removal and destruction of the infested bud.
