Flies in peony stems
The cut tips of several peony stems had signs of borers--I could see the inside material of the stem powdered and on the lower leaves. I split a stem in half and found several small flies inside the stem. They showed no sign of life. I am pretty sure they are small flies--they have the typical fly shaped wings and large eyes. I am just so curious to learn more about the life cycle of these flies. I have about 6 more peony stems with the same signs of borers. Anyone know what they are?
