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?………

Many thanks,
