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.

Aspen is well-adapted to 🔥︎ fire—after a fire, it produces new trunks from the its roots or trunk base.  Aspen often grows with jack pine  Pinus banksiana —after a fire, both grow fast and eventually would get shaded out by spruce  genus Picea and fir  genus Abies, until again invig­or­ated by the next cycle of fire.
