Dunn Executive Secretary M. C. Nielsen Journal Editor D. C. L. Gosling Newsletter Editor Louis F. Wilson The Michigan Entomological Society traces its origins to the old Detroit Entomological Society and was organized on 4 November 1954 to " ... promote the science ofentomology in all its branches and by all feasible means, and to advance cooperation and good fellowship among persons interested in entomology." The Society attempts to facilitate the exchange of ideas and information in both amateur and professional circles, and encourages the study of insects by youth. Membership in the Society, which serves the North Central States and adjacent Canada, is open to all persons interested in entomology. There are four paying classes of membership: Student (including those currently enrolled as college sophomores)-annual dues $4.00 Active-annual dues $8.00 Institutional-annual dues $18.00 Sustaining-annual contribution $25.00 or more Dues are paid on a calendar year basis (Jan. I-Dec. 31). Memberships accepted before July 1 shall begin on the preceding January I; memberships accepted at a later date shall begin the following January 1 unless the earlier date is re­ quested and the required dues are paid. All members in good standing receive the Newsletter of the Society, published quarterly. All Active and Sustaining Members may vote in Society affairs. All dues and contributions to the Society are deductible for Federal income tax purposes.

Weber,2 and T. 1. Henry3 ABSTRACT The seasonal flight patterns of 79 species of Miridae collected in window traps in a North Carolina black walnut plantation are described. Flying height distributions and seasonal flight activities of Deraeocoris nebulosus (Uhler), Keltonia sulphurea (Reuter), Lygus lineo/aris (Palisot de Beauvois), Plagiognathus poUtus Uhler, and Reuteroscopus ornatus (Reuter) are considered in detail. This is the last in a series of papers on seasonal flight patterns of Hemiptera in a black walnut (Jug/ans nigra L.) plantation near Asheville, North Carolina, and deals with the family Miridae; earlier papers dealt with the Pentatomoidea (1980), Coreoidea (l98Ia), Reduvioidea (l981b), Cimicoidea (l98Ic), Lygaeoidea (l98Id), and Tingidae and Aradidae (198Ie). The study was conducted from 24 March to 14 October in 1977, and from 24 March to 13 October in 1978. Specimens were collected weekly by window trapping; traps were suspended at 1, 2, 3, 4, 5, 6, and 7 m. The study site and trap construction are discussed in detail by McPherson and Weber (1980). All hemipteran specimens collected during this study are deposited in the Entomology Collection, Zoology Research Museum, Southern Illinois University, Carbondale. RESULTS AND DISCUSSION Seventy nine mirid species were collected during the two years of this study with the subfamily Mirinae being best represented; numbers of specimens eollected for all taxa ranged from I to 2673 (Table I). Most of the species were collected in numbers too low to permit conclusions about seasonal flight patterns. However, Deraeocoris nebulosus (Uhler), Keltollia su/phurea (Reuter), Lygus lineolaris (Palisot de Beauvois), P/agiogllathus POlilUS Uhler, and Relitero­ scopus ornatus (Reuter) were collected in sufficient numbers (Table 1) to allow a more detailed discussion of flying height distributions and seasonal flight activities. D. Ilebulosus, a predaceous species, is generally associated with trees and shrubs (Wheeler et al. 1975). It has been reported to attack various species of mites and insects including, among others, European red mite, Panollychus ulmi (Koch); woolly apple aphid, Eriosoma lanigerum (Hausmann); clover aphid, Nearctaphis bakeri (Cowen); hop aphid, Phorodoll humuli (Schrank); cotton aphid, Aphis gossypii Glover; terrapin scale, Lecanium nigrofasciatum Pergande; eyespotted bud moth, Spiionota ocellana (Denis and Schiffer­ muller); and possibly codling moth, Laspeyresia pomollella (L.) (see literature survey of Wheeler et al. 1975). Wheeler et al. (1975), in their study of this insect, also reported its feeding on the mite Oliogonychus bicoior (Banks); the oak lace bug, Corythucha arcuata I Department of Zoology, Southern Illinois University, Carbondale, IL 6290 L 2USDA Forest Service, North Central Forest EXperiment Station, Forestry Sciences Laboratory, Carbondale, IL 62901. 3Systematic Entomology Laboratory, lIBllI, Agricultuml Research Service.
