snout bug or beetle
These are common in grasslands around Boulder, Colorado, and I’m embarrassed that I can’t find them in any field guide. Much thanks,
This is a Fulgorid Planthopper, commonly called a Lanternfly. A common Eastern species, Scolops sulcipes, is known as the Partridge Bug. Our Audubon Guide lists a species, also from the east, Scolops perdix, the Partridge Scolops, but we cannot locate that species name on BugGuide. BugGuide does list a species from Colorado, Scolops hesperius, bug on the page, Andy Hamilton writes: ” This species has a shorter, stouter horn on the head than other Scolops. It is a western species.” Your photo depicts a longer, narrower horn, much like the eastern species. We will contact Eric Eaton to see if he can provide the exact species.
