Insects of Cedar Creek

Order HOMOPTERA

Family MEMBRACIDAE

(Treehoppers)

(Table of Species)

The Treehoppers (258 NA spp) are most diverse in wooded habitat. Nearly 45 species have been collected at CCESR, but taxonomic IDs are uncertain for several. Only a few species are common in old fields. This Group will be discussed by Subfamily.

CENTROTINAE
Microcentrus sp  has been collected from Bur Oak.

MEMBRACINAE
Campylenchia latipes is fairly common on weedy Asteraceae. This species is small, dark brown, with pronotum extending hornlike over the head.  Only a few specimens of Enchenopa binotata have been collected from Black Cherry.

SMILIINAE--POLYGLYPTINI
Publilia modesta is sometimes found in abundance on Solidago gigantea and Artemisia ludoviciana. This small species is extremely polymorphic in coloration--ranging from pale green to dark brown. Publilia concava is more at home on Circium and Helianthus in shaded situations.  Entylia bactriana is a small dark species with the dorsal crest deeply notched.   Vanduzea triguttata is a small hairy species that is sometimes found in abundance on lead plant (Amorpha canescens) or purple prairie clover (Petalostemum purpureum) in savanna regions.

SMILIINAE--CERESINI
Species of shrub-feeding Stictocephala (ca 7 spp) are common in savanna regions in the fall. These species are Green or Brown with pronounced humeral horns on the hoodlike pronotum.  Species collected include: S. bubalis, S. taurinus, S. diceros, S. brevitylus, S. basalis, S. lutea, and S. ?palmeri. Stictocephala lutea (Tortistilus inermis?) is a common species taken from a variety of fields in late spring.

SMILIINAE--SMILIINI
Smilia camelus is a woodland species that feeds on the foliage of young Pin Oaks (Quercus ellipsoidalis).  It is laterally compressed with a fair sized pronotal crest.  Numerous individuals of oak-inhabiting species of Ophiderma (5 spp--definita, flava, grisea, pubescens, salamandra) and Cyrtolobus (6+spp incl. discoidalis, ?fuscipennis, maculifrontis, puritanus, vau, arcuatus, pulchellus?)) as well as Atymna querci have been collected. These genera readily come to light.

SMILIINAE-TELAMONINI
Members of this Tribe are large, attractive species with distinctive pronotal crests.  Archasia auriculata, with a large green convex hood, is  reported to feed on Pin Oak. Thelia bimaculata is found on Black Locust, where adults and nymphs are tended by the ant, Formica obscuripes.  This large brown species has a thorn-like horn extending over the head, and the males are adorned with lateral yellow racing stripes. Carynota marmorata is a large maroon species with no pronotal crest.  It has been taken from Paper Birch.  Species of Glossonotus have a slender, rounded, vertically projecting crest.  2+spp of Glossonotus including univittatus, nimbalis have been collected.  Species of Heliria (2+spp incl. molaris, gemma) have a step-like pronotal crest. Finally, species of Telamona (5+ spp incl compacta, monticola, spreta, unicolor, westcotti) have a large pyramidal crest. All of these species occur on woody shrubs or trees. See Species Table for host information.
