Robinia hosts caterpillars of 59 species
of butterflies and moths, in some areas.
  This plant is also known to be a host for (in areas where invasive) 🐝︎ spotted lanternfly (SLF)  Lycorma delicatula.

Like most legumes, this plant cooperates with a bacterium that fixes atmospheric nitrogen into a form usable by plants and animals.

That allows these plants to:

  • outcompete non-nitrogen-fixing plants in poorer soils, or
  • have seeds and foliage with more protein.

This makes their seeds and foliage more nutritious to plant-eaters.  And growing these plants may improve the quality of worn-out farmland and disturbed soils.

Often grows in clonal colonies [1] — look around for other stems!
