Thank you. Google images show a similar patern. Never knew they were such artists.

IMO you may
need to consider another cause for the damage to the canna leaf instead of the
canna leaf roller. I immediately considered the leaf roller at first look and
that is a possibility but in this case I believe you may consider our common grasshopper
as the offender.

Grasshoppers
are never a major concern in regard to cannas but they can and do produce this very
damage to emerging rolled up canna leaves. If you notice the hole damage is
much larger on the far left and becomes progressively smaller going across the
leaf. This result is inconsistent with the typical leaf roller damage.

Just another
thought.

Still going with the leaf roller; their damage would often be described as 'perforated', unless very serious.

Never knew they were such artists.

==>> i dont know what art is involved in eating straight thru a rolled leaf ...

roll up a sheet a paper.. and poke a hole thru it.. unroll paper.. they will be in a straight line ... are you now an artist.. lol ..
