Description: A grayish-brown species that is highly variable in coloration with several color forms, typically with zig-zag lines of various darkness cross the wings (varying among individuals, see pics above). Both the thorax and face are unicolorous and dark; the frons (upper part of face) and clypeus (lower part) are similarly colored, typically a dark blackish color but can be variable; the dark frons color is a key characteristic. The legs are a brownish color. Adults range a little larger than 6 mm long. For images of a pinned specimen, see here. Adult males are 5.3-6.0 mm long, while females are 6.0-6.5 mm. (Kramer 1981)

Distribution: A very common species found in eastern and central United States and Canada (UDEL)
Abundance: Primarily recorded from the mountains where it can be common, but recorded from a couple counties in the Piedmont. Likely widespread throughout the NC mountains.

Habitats and Life History
Habitats: Montane
Plant Associates: "Nymphs of cixiids are subterranean, feeding on roots and possibly fungi. The significance of adult host records is unclear. Many cixiids are presumed to be polyphagous (as adults), most often on woody plants." Adults have been recorded from Gaylussacia, Pinus, Picea, and Abies (UDEL)
Behavior:
Comment: This species can be confused with C. nervosus. It is especially important to obtain a view of the underside, as the frons color can differentiate these two species: in pini, the face is typically entirely black, whereas in nervosus the face ranges from having a contrastingly pale clypeus to being entirely light in color. Additionally, males of nervosus have a characteristic hook projection on the anal tube that is easily seen without dissection. Otherwise, there are no reliable external ways to separate the species (C. Bartlett pers. comment)

This species also superficially resembles C. coloepeum; a species ID may not always be possible for individuals that may represent one of these two species. Charles Bartlett notes "I have tried hard to find a consistent difference between pini and coloepeum - I think there must be - but I have always dissected to be sure" (pers. comment). Cixius can be very difficult to ID.
