Tree of Heaven, Ailanthus altissima, is a highly invasive tree species originally from China and Vietnam. It is the preferred host of Spotted Lanternfly, an invasive leafhopper from China and adjacent countries.

This insect is a serious threat to Ohio vineyards, orchards, and vegetable farms- and many trees, such as maples. Spotted Lanternfly threats plants sucking up the plant juices. In a similar fashion, they damage trees as they suck their juices. This does not directly kill the trees, but repeated attacks allow diseases into the damaged trees which leads to decline. 

This invasive tree has very long compound leaves that may be confused with hickory or similar native trees. It has separate male and female trees. Female trees produce prolific winged seeds. They are also spread by underground roots, especially if the tree is cut down or injured. 

Spotted lanternflies have been found in Cuyahoga and Lorain Counties. Often egg cases are laid on railroad cars which contribute to the distribution of the insects. You know Berea has a few rail lines! Some Spotted Lanternfly egg cases were found on the east side of Cleveland and also found (and removed) near Rocky River, Ohio- right down the river from Berea. Tree of Heaven have been spotted in Berea along Coe Lake and at the Triangle.  We need help in identifying the nymphs which hatch in late spring. This prevents them from becoming adults to lay eggs in late summer to fall.

It is important to find local Tree of Heaven specimens that attract Spotted Lanternfly. If you see Tree of Heaven or any stage of Spotted Lanternfly, report them to the Ohio Department of Agriculture at [email protected] and Sustainable Berea at [email protected].
