This new genus is characterized by the large body; large and strong mandibles; short labrum; elytra without longitudinal carina; and male meso- and possible metatibia apically modified. A list of described fossil glaphyrids of the world is provided. ...

During 1995 to 2001, two research trials and two farms in the Midlands region of the industry were monitored for yield effects attributable to whitegrub (various species of Scarabaeoidea). Although the trials were designed for other purposes, severe whitegrub infestations were observed in the soils on which the trials were situated, and the opportunity was taken to assess the impact of this soi...

The adult edible beetle Holotrichia parallela Motschulsky (Coleoptera: Scarabaeoidea) represents a traditional food source in China. Based on nutritional analyses, adult H. parallela is high in protein (70%) and minerals and low in fat. H. parallela contained approximately 10% chitin; the corrected protein content was 66%. Oleic acid and linoleic acid were the most abundant fatty acids. Of the ...

The external morphology of sensilla on the antennae of males and females of Phyllophaga ravida Blanchard is described using scanning electron microscopy. Sexual dimorphism in body and antennal dimensions and in antennal receptor types was found. The female's body is slightly larger than the male's, although male antennal lamellae are longer than in females. Sixteen types of sensilla were identi...

There are recent faunistic surveys of selected insect taxa (e.g. Mutillidae, Scarabaeoidea, and Tenebrionidae) in Wisconsin but a formal investigation of the Meloidae (blister beetles) is lacking. The blister beetle fauna of several states has been published, but this study represents the first in the Midwestern United States. We provide a comprehensive list of all meloid species documented fro...
