This time of year tulip poplar leaves are covered in aphids. The great thing about tulip poplar aphids is that they attract a diverse array of predators and that can help control other pests. Therefore, after a few weeks of dowsing your sidewalk in honeydew the aphids almost disappear. Here is a tulip poplar leaf that foreshadows the aphids demise. It has lots of aphids but also lady beetle eggs and a parasitoid mummy. On the same tree I found syrphid fly larvae, green lacewing larvae and eggs, and other predators. Thus, I don’t feel any management is usually necessary for these aphids. They support many natural enemies which often have a hard time living in urban landscapes.
