Life History of \u3ci\u3eCeratocombus Vagans\u3c/i\u3e (Hemiptera: Heteroptera: Ceratocombidae), With Notes on the Immature Stages

The biology and life stages of Ceratocombus vagans are given together with distributional notes. The current systematic position of Ceratocombidae is reviewed. This species is one of the most generalized Hemiptera: Heteroptera known. Its predatory habits lend credance to the idea that primitive Hemiptera: Heteroptera were predaceous as suggested by Stys and others. Ceratocombus vagans occurs in moss, leaf litter, and under loose bark. It has wide distribution in much of North America

Dead Leaf Clusters as Habitats for Adult \u3ci\u3eCalliodis Temnostethoides\u3c/i\u3e and \u3ci\u3eCardiastethus Luridellus\u3c/i\u3e and Other Anthocorids (Hemiptera: Heteroptera: Anthocoridae)

Two species of Anthocoridae (Hemiptera: Heteroptera) were found in dead-leaf clusters of black oak in west-central Michigan, Calliodis temnostethoides and Cardiastethus luridellus. These clusters resulted from full- leafed trees being blown over by a severe wind storm in May 1998. They contained spiders, springtails, tubiliferan thrips, small beetles, and psocids, besides the predaceous anthocorids. Such habitats are well-known for some bugs elsewhere. Because only adults were collected, it was assumed that the more permanent habitat was likely to be under bark. Further attention to this habitat likely will result in additional records for other species of Anthocoridae

\u3ci\u3eArhyssus Hirtus\u3c/i\u3e (Hemiptera: Heteroptera: Rhopalidae) in Minnesota: The Inland Occurrence of an East Coast Species

Arhyssus hirtus (Hemiptera: Heteroptera: Rhopalidae), is reported from the Cedar Creek Natural History Area, a Long-Term Ecological Research site, outside of Minneapolis, Minnesota where over 4000 species of arthropods have been collected. This species has previously been known only from a narrow zone along the sandy edges of the Atlantic Ocean (Maryland, Massachusetts, New Jersey and New York). The species is known on Hudsonia tomentosa at these ocean sites, but other hosts may be involved at Cedar Creek. This small species of Arhyssus occurs in both micropterous and macropterous forms, unusual for this genus. Thus far, only micropterous forms have been collected at the Minnesota site
