iris fly?

Hello Janos- I've grown irises for more than 35 years (but in the U.S.) and
have never seen the insect you describe, nor the kind of damage you show in
your photo. It may be something new to your area or peculiar to that one
shipment. I think you are wise to burn the affected leaves.

Dear All,
Today I've found some larvae inside of my iris leaves, they made holes
inside and between the 2 epidermis. I think it is a kind of fly becouse
the
pupa is like a small brown rice. I have never seen this before, they came
with new plants from a nursery. The larvae are chewing downwards some of
them may reached the soil level. It is no use of any insecticides, becouse
they are not feeding any more. I try to collect the leaves and burn.
Does anybody know what is this? Did anybody ever saw symptoms like this?
