Ratcliffe and Mary Liz Jameson Systematics Research Collections W436 Nebraska Hall, University of Nebraska Lincoln, NE 68588-0514 [email protected] and [email protected] Considering the turmoil and vast changes in the classification of the superfamily Scarabaeoidea during the last 20 years, particularly in North America, we were asked to provide an update for the readers of Scarabs wherein we offer our perspectives. Much of what follows is extracted from our scarabaeoid introduction in American Beetles (Jameson and Ratcliffe 2002). By the time this overview is printed, there may have been more changes in the classification because of the rapidly accumulating evidence supporting new hypotheses. These rapid changes are a result of intensified study of the family groups using both traditional morphological evidence combined Brett and Mary Liz with increasingly insightful The superfamily Scarabaeoidea molecular studies. While possibly is a large, diverse, cosmopolitan disruptive now, these new studies group of beetles. As a personal are exciting because, for the aside (and, of course, with no first time, we are establishing bias), these are probably the finest the higher classification of the beetles in the world. Scarabaeoids Scarabaeoidea based on evidence are adapted to most habitats, and facts rather than intuition. and they can be fungivores, This research confirms many of herbivores, necrophages, our hypotheses of classification coprophages, saprophages, and Ed.

Scarabaeoids are the “traditional” North American popular beetles due to their large system and had several practical size, bright colors, and interesting and conceptual advantages. First, natural histories.
