Rhododendron gall midge (Clinodiplosis rhododendri).
Dwarfed, distorted foliage caused by Azalea Midge.
Damage to normal sized leaves is also evident.
Witches broom on the left, normal growth on the right.
Since I use as few insecticides as possible in the garden, I am going to cut off and dispose of all foliage with signs of midge damage while the weather has turned cold and dry.
An azalea on the other end of the bed which was not cut
back is beginning to show bud color.
