Macrodactylini

Katovich, Kerry, 2008, A generic-level phylogenetic review of the Macrodactylini (Coleoptera: Scarabaeidae: Melolonthinae), Insecta Mundi 2008 (23), pp. 1-78 : 4-5

Distribution of Macrodactylini

The newly defined Macrodactylini are distributed across the New World. The vast majority of macrodactyline genera are centered in Southern Brazil, with several genera extending into Central and North America. Distributional limits remain unclear for the vast majority of genera, with adequate distributional information recorded only for a modest number of North American, Caribbean, and Central American species.

General Life History of Macrodactylini

Little is known of the life histories or food plant associations of macrodactyline species. Limited information suggests members of this tribe feed on root tissues as larvae and plant parts (leaves and flowers) as adults. Anecdotal evidence suggests larvae prefer well-drained soils with some organic materials in which to develop and feed. Adults of this tribe are known to exhibit both nocturnal and diurnal activity patterns.

Taxonomic Methodology and Materials

Specimens used in this study were provided by 14 primary institutions. Acronyms for loan institutions follow Arnett et al. (1993). Syntypes and homeotypes examined by the author were labeled with a species identification label and their location is noted. Holotypes and paratypes examined were not labeled; their location is provided in this manuscript.
