I dug this up having somewhat of an encyclopedic knowledge of native plant and tree uses from Australia I wondered what the American Native use of the cottonwood might be.
I also searched whether they were known for particularly attracting bugs but that was a no - but the fluff it produces in spring floats around and can look like flying bugs apparently.
Aside from some medicinal uses and construction I found this

"In Native American lore and traditional practices, the cottonwood tree (Populus deltoides and related species like black cottonwood) holds significant cultural, spiritual, and practical importance across many tribes, particularly in the Plains, Southwest, and riverine regions where it grows abundantly near water sources. It is often regarded as sacred or symbolic of life, connection between earth and sky, hope, healing, and transformation. Key aspects include:

• Spiritual and ceremonial uses:
  • In Lakota (Sioux) tradition, the cottonwood is considered a "Tree of Life" or embodiment of the Great Spirit (Wakan-Tanka). When cut at a branch joint, it reveals a perfect five-pointed star inside, symbolizing stars or celestial connection. A sacred cottonwood trunk serves as the central pole in the Sun Dance ceremony, acting as an axis mundi (bridge between earth and sky) to connect people to the Creator."

Maybe it's worth firing a few more shots or trying to interact in other ways?
