Insects of Cedar Creek
Order HEMIPTERA
Family PENTATOMIDAE
(Stink Bugs)
(Table of Species)
SCUTELLERINAE
Two species of Homaemus
occur in CCESR old fields. H. aenifrons has an entirely black
face, and H. bijugis has a pale yellow line on each cheek.
H. bijugis is the more common of the two. Some individuals
have faint facial stripes, and it is possible these two species hybridize?
Homaemus spp are fairly common in a variety of field types, but
seem shoewhat more numerous in xeric sites.
Eurygaster
alternatus is less common, but has also been collected in a
variety of fields. Phimodera
binotata is a rare species that has only been collected in
extremely xeric fields. Members of these genera probably feed on
grass seeds. Tetyra bipunctata
is an uncommon large Scutellerid that feeds on seeds in pine cones.
ACANTHOSOMATINAE
These Stink Bugs are generally golden with red markings. Elasmucha
lateralis occurs on birch in woodlands where the females guards
her nymphs. Elasmostethus cruciatus
occurs on alder in swamps, and
Elasmostethus atricornis is
an uncommon species found on
Aralia in woodlands.
PENTATOMINAE
A single uncommon? species of Turtle Bug, Amaurochrous
brevitylus?, occurs in marshes. It is suspected to feed
on cattail heads. This species is small, dark, with an enlarged scutellum,
resembling the Scutellerinae. Brochymena
quadripustulata and Brochymena
arborea are uncommon tree/shrub inhabitants that are suspected
to be predaceous. The are flattened, jagged-edged and dark resembling bark.
Mecidea
major is a pale elongate Pentatomid that is reported to feed
upon
Bouteloua curtipendula. This species is a new state record
taken only in E (xeric
Aristida).
The following species are large and green. Banasa dimidiata is a common woodland species. Acrosternum hilare is another wood edge species that feeds on Prunus and Amelanchier fruit. Thyanta accerra ? was taken in three fields but only in 1990. Pitedia persimilis has been collected in small numbers from a variety of fields but appears to be more common in xeric sites. I suspect it may feed on Vicia villosa and/or Lathyrus venosus seed pods.
Cosmopepla bimaculata is a small black and red species often found on Hedge Nettle (Stachys palustris) or mullein (Verbascum thapsus). Pitedia ligata? is a rare large black and red-bordered species collected only in 1988? Mormidea lugens is a small black and bronze species with scutellum outlined in yellow. It is fairly common. Dendrocoris humeralis is an uncommon red-tinged woodland species.
The following species have the scutellum nearly equalling the coria in length. Neottiglossa undata is apparently a rare species on the Area. It has only been taken in a few fields. It is abundant in Poa fields across the state. Coenus delius is relatively common in a variety of fields. Aelia americana is somewhat less common but still widespread. It appears more abundant in brome fields. These species are all suspected to feed on grass seeds.
Trichopepla atricornis? is an uncommon pentatomid with erect hairs on the dorsum. Holcostethus limbolarius is common and widespread but more abundant in xeric and weedy sites. Three species of Euschistus have been collected from CCESR old fields. E. variolarius has pointed humeral angles and juga and tylus are equal in length. E. servus-euschistoides has rounded humeral angles and the juga exceed the tylus. Both are relatively common in a variety of field types. E. ictericus has a callous ridge running between its pointed humeri. It is considerably less common. A fourth species of Euschistus, E. tristigmus, is a common woodland species often found on cherry and juneberry.
ASOPINAE
As mentioned earlier, members of this family are predaceous--generally
on Coleoptera or Lepidoptera larvae. All are rather infrequently encountered.
Perillus
circumcinctus, marked with maroon and white, has been been
observed feeding on adult and larval Trirhabda in a few fields.
Stiretrus
anchorago, a robust Calligrapha-like fellow, has been observed
feeding on Blepharida larvae on sumac clones at field edges. Small
numbers of three species of Podisus
(placidus,
modestus,
brevispinus)
have been collected. A few individuals of the large Apateticus
cynicus have also been collected.
