Ecological Role

The American Elm is the larval host of a number of species of Lepidoptera, including such butterflies as the Eastern Comma (Polygonia comma), Mourning Cloak (Nymphalis antiopa), Painted Lady (Vanessa cardui) and Red-spotted Purple (Limenitis arthemis astyanax), as well moths like the Columbian Silkmoth (Hyalophora columbia).

Endangered

Threats & Impacts

Dutch elm disease (DED), a fungal disease that has ravaged the American elm, causing catastrophic die-offs in cities across the range. It has been estimated that only approximately 1 in 100,000 American elm trees is DED-tolerant.
