Moved from Basswood Treehopper.

I couldn't find any web reference to Lime Treehopper as a common name for this species; did you find the name in a book, perhaps? I'm thinking that the species epithet "tiliae" may refer to the tree genus Tilia, but the most widespread North American species - Tilia americana - is commonly called American Basswood (or American Linden by horticulturalists). The alternate name of Lime Tree is rarely used, probably because it's too easily confused with Citrus aurantifolia, the Lime Tree that produces the limes sold in grocery stores.

Sorry, my mistake ... Telamona tiliae has a narrower crest and lacks the yellow spots freckling the dark ground color, which is typical of T. monticola (an oak feeder).
