There are 3 species of butterfly in PA that use Hackberry as a larval food plant: Hackberry emperor, Tawny emperor, and the American snout butterfly. I have seen all 3 species in my yard in Perry Co., with the first being the most common. According to David Wright's Atlas of PA Butterflies, all 3 species are found across the lower 2/3s of the state excluding the Laurel Highlands.

Subject: [PABIRDS] Hackberry Trees: Bedford Co.
I've also enjoyed the thread about birds feeding on hackberry trees. A long time ago, we found one fruit-bearing, but very scrawny hackberry tree on our property in Bedford Co., so we decided to plant more hackberry trees. They are now about 15 years old and at least 30 feet tall. They look healthy, but have never bloomed or produced fruit.
In addition to supplying food for birds, hackberry trees are the only host plant for the hackberry emperor butterfly. Has anyone seen this butterfly in Pennsylvania? We never have and we are hoping to attract it, as well as the birds.
Does anyone on this list have experience growing hackberries? I'd love to get some suggestions on how to "persuade" our hackberries to bloom.
