My Sambuca Tree Is Covered In Tiny Midge Type Insects And White Powder And Looking A Bit Droopy.

Question

It is about 5 years old and 5 feet high and up to now has been healthy.

Answer 1

You may be seeing aphids, which sometimes have wings. A powdery substance could be powdery mildew.

Another possibility is mealybugs, which leave a white substance.
