An Annotated List of the Cerambycidae of Michigan (Coleoptera) Part II, the Subfamilies Lepturinae and Lamiinae

(excerpt) This is a continuation of Part I of an annotated list of the Cerambycidae known from Michigan, and includes the remaining subfamilies Lepturinae and Lamiinae. The format is similar to that used in Part I. We have largely followed the systematic order of Chemsak and Linsley (1975) in this part of the list. Keys for the identification of adult Lepturinae can be found in Linsley and Chemsak (1972; in press). References to keys for adult Lamiinae are listed under that subfamily. Many larvae may be identified through the keys in Craighead (1923), but not all Michigan species are covere

Guidelines for peer observation of learning and teaching

These guidelines have been prepared as a starting point for schools of education or education departments wishing to undertake peer observation of learning and teaching, particularly as preparation for a Subject Review. While the guidelines are designed to have general applicability to any department, the particular circumstances and the requirements of specific subjects will almost certainly mean that there will be variations in practice between departments and subject area

An Annotated List of the Cerambycidae of Michigan (Coleoptera) Part I, Introduction and the Subfamilies Parandrinae, Prioninae, Spondylinae, Aseminae, and Cerambycinae

The Cerambycidae are generally acknowledged as one of the most popular families of Coleoptera, and it is not surprising that they have been collected widely in Michigan. Andrews (1916, 1921, 1929), Hatch (1924), Hubbard and Schwarz (1878), and Wickham (1895), included Cerambycidae in published lists of insects from various localities in the state. The present list, however, is the first to include records of collections made throughout Michigan. Some regions of the state have been rather thoroughly collected, particularly the southeastern counties. Collecting throughout Michigan has been sufficient to consider this list as essentially complete, although continued studies in the southwestern Lower Peninsula and the western Upper Peninsula will undoubtedly add a few species to the records

Minimum wages: possible effects on the distribution of income

Since the 1980s, there has been increased interest among unions and two opposition parties in the possibility of introducing a national minimum wage (NMW). The central argument for a minimum wage is a social justice one: a minimum wage is deemed necessary to prevent some employers exploiting workers with little bargaining power by paying them less than the value of the goods and services they produce. The aim of this paper is to establish what sort of people might be affected by a minimum wage, how this might have changed over time and how far a minimum wage can be used as a tool to redistribute income from the rich to the poor. No attempt is made to simulate the effect of a NMW on employment and prices, and obviously any complete analysis needs to take these effects into account. Recent research (see the discussion below) on this issue, however, indicates little evidence that a `moderate\\\' minimum will have any effect on employment and it is thus likely that the ‘first-round effects\\\' described in this paper are informative.

Flower Records for Anthophilous Cerambycidae in a Southwestern Michigan Woodland (Coleoptera)

Flower records are listed for 33 species of anthophilous Cerambycidae based on a six-year study in an 80-ha woodland in southwestern Michigan. Included is the first published flower record for Gaurotes thoradca, taken from Cornus racemosa

Ecology of the Cerambycidae (Coleoptera) of the Huron Mountains in Northern Michigan

Eighty-nine species of Cerambycidae were collected during a five-year survey of the woodboring beetle fauna of the Huron Mountains in Marquette County, Michigan. Host plants were determined for 51 species. Observations were made of species abundance and phenology, and the blossoms visited by anthophilous cerambycids

Cerambycid Host Plants in a Southwestern Michigan Woodland (Coleoptera: Cerambycidae)

Host plant associations are listed for 61 species of Cerambycidae based on a six-year study in an 80-ha woodland in southwestern Michigan

Correct Identity of the Oak Twig Pruner (Coleoptera: Cerambycidae)

(excerpt) The oak twig pruner is a cerambycid of minor economic importance which is generally common through most of eastern North America. The adult beetles oviposit on living twigs of oak and other hardwoods, and the larvae bore within the twig, subsequently pruning it from the tree. Haldeman (1847) identified this borer as Elaphidion villosus (Fabricius), a species later placed in the genus Elaphidionoides by Linsley (1963). This identification has been accepted and followed by Baker (1972), Craighead (1923, 1950), Duffy (1960), Knull (1946). Linsley (1963), and many other authors

Observations on the Biology of the Oak Twig Pruner, \u3ci\u3eElaphidionoides Parallelus,\u3c/i\u3e (Coleoptera: Cerambycidae) in Michigan

(excerpt) The oak twig pruner, Elaphidionoides parallelus (Newman) (Coleoptera: Cerambycidae) is rather common in southern Michigan where it attacks living oaks and other hardwoods. The damage it inflicts is rarely serious, but it may be considered a pest insect if only for the nuisance it creates for those who must clean up the often numerous small branches pruned from street, lawn, and park trees

New State Records of Cerambycidae From Michigan (Coleoptera)

(excerpt) Previously published lists of Cerambycidae from Michigan (Gosling 1973, Gosling and Gosling 1977) recorded 225 species from the state. Reassignment of Trachysida brevifrons (Howden) as a subspecies of Trachysida aspera (LeConte) (Linsley and Chemsak 1976) reduced the total by one. Recent collecting in St. Joseph County in southwestern Michigan and Marquette County in the Upper Peninsula has added three species to those already known from Michigan
