Insects of Cedar Creek

Order COLEOPTERA

Family CERAMBYCIDAE

(Longhorn Beetles)

(Table of Species)

More than 50 species of Long-Horned Wood Borers (956 NA spp) have been collected at Cedar Creek. Adults are a favorite among collectors, and  many more await some avid collector. Most species are associated with dead/decaying hardwoods in woodlands. Larve are called Round-headed Borers and leave circular exit holes.
225 species have been collected in Michigan (Gosling, 1973, 1976) and it is likely that a comparable number occur in Minnesota.  At present, the U/MN Collection in St. Paul holds 170+ species with Minnesota locality labels.
I thank Phil Clausen (Univ. Minn., St Paul Campus) for determining many of these specimens.  Representatives of the five subfamilies collected are discussed below.

PARANDRINAE
Parandra brunnea-brunnea has been taken in pitfall in mesic woodland.

PRIONINAE
Prionus and Tragosoma are present in Minnesota, but this Subfamily has not been collected at Cedar Creek.

ASEMINAE
Asemum sp has been collected.  Genera represented in Minnesota but not collected at Cedar Creek include: Arhopalus and Tetropium.

CERAMBYCINAE
The red Batyle suturale is fairly common on Rudbeckia in late summer. Molorchus bimaculatus is common on Prunus/Amelanchier blooms in early spring. Small numbers of the following species have been collected: Elaphidionoides (3 spp--villosus, parallelus, incertus), Callidium sp, Megacyllene robiniae Sarosethes fulminans, Xylotrechus (3+spp--sagittatus, colonus, undulatus), Neoclytus muricatulus, Clytus ruricola, Cyrtophorus verrucosus, Euderces picipes... (see Species Table for host preference).
Numerous other genera are reported for Minnesota but have not been collected at Cedar Creek.  These include:  Calloides, Eburia, Enaphalodes, Glycobius, Hesperophanes, Hylotrupes, Heterachthes, Knulliana, Meriellum, Microclytus, Obrium, Pronocera, Psyrassa, Physocnemum, Phymatodes, Purpuricenus, Stenosphenus, Tylonotus...

LEPTURINAE
Most of these species are quite colorful and of moderate size with tapering elytra. Many occur on flowers. Species collected include: Strangalia (luteicornis, famelica), Bellamira scalaris, Charisalia americana, Grammoptera (exigua, subargentata) Typocerus (velutinus, sparsus), Analeptura lineola, Brachyleptura (rubrica, vagans), Trachysida mutabilis, Strangalepta vittata, Trigonarthris proxima, Strophiona nitens, Stictoleptura canadensis, Lepturopsis biforis, Stenocorus inquisitor?, and Cosmosalia chrysocoma. The most common species in this subfamily are T. velutinus, A. lineola, B. vagans, T. mutabilis, and S. vittata.
Numerous other genera are reported for Minnesota but have not been collected at Cedar Creek.  These include:  Achmaeops, Alosternidia, Anastrangalia, Anthophylax, Brachysomida, Desmocerus, Evodinus, Gaurotes, Gnathacmaeops, Idiopidonia, Judolia, Metacmaeops, Necydalis, Pachyta, Pseudostrangalia, Pidonia, Pygoleptura, Rhagium, Sachalinobia, Xestoleptura...

LAMIINAE
Members of this Subfamily are generally elongate cylindrical and rarely occur at flowers, but some are attracted to light. Three species of red-and-black Tetraopes, Milkweed Longhorn Beetles, are found in old fields. T. tetraophthalmus(many BK elytral spots) and T. quinquemaculatus (only five elytral spots) have black antennae and T. femoratus has black antennae with white annuli. Four species of Oberea (bimaculata, ocellata, schaumi, ulmicola) have been collected. O. bimaculata bores into Rubus shoots and O. ocellata girdles new shoots of sumac. Monochamus (2+spp--notatus, scutellatus) are large attractive beetles that feed on dead pine. Others collected include: Goes pulverulentus, Psenocerus supernotatus, Graphisurus fasciatus, Amniscus sexguttata, Sternidius alpha, Hyperplatys aspersa, and Saperda spp (obliqua). Most of these bore into dead/dying twigs.
Other genera represented in Minnesota but not collected at Cedar Creek include:  Aegoschema, Astyleiopus, Dectes, Dorcaschema, Ecyrus, Eupogonius, Hemierana, Hetoemis, Leptostylus, Lepturges, Neocanthocinus, Pogonocherus, Urgleptes...
