Thermoregulation in endothermic dung beetles (Coleoptera: Scarabaeidae): effect of body size and ecophysiological constraints in flight.

Absence of endothermy in flightless dung beetles from southern Africa

Endothermy in insects is normally associated with flight but has been observed during strictly terrestrial activity in beetles (Bartholomew & Casey 1977a, b). A study by Bartholomew & Heinrich (1978) in Kenya showed that dung beetles are conspicuously endothermic during flight, ball making and ball rolling, and sometimes while walking. Endothermy during terrestrial activity is probably advantag...

Diel flight activity and ecological segregation within an assemblage of tropical forest dung and carrion beetles

Temporal variation in activity of dung and carrion beetles in tropical forest is considered as a mechanism of ecological segregation between potentially competing species. We describe the diel flight activity of Scarabaeidae collectedwithbaitedpitfall trapsatLesNouraguesfieldstation inFrenchGuiana.Atotalof2663individualsof63species was recorded, from the subfamilies Coprinae, Scarabaeinae andAp...

Sexual shape dimorphism accelerated by male–male competition, but not prevented by sex-indiscriminate parental care in dung beetles (Scarabaeidae)

Dimorphic sexual differences in shape and body size are called sexual dimorphism and sexual size dimorphism, respectively. The degrees of both dimorphisms are considered to increase with sexual selection, represented by male-male competition. However, the degrees of the two dimorphisms often differ within a species. In some dung beetles, typical sexual shape dimorphisms are seen in male horns a...

Composition and Distribution Patterns of Species at a Global Biogeographic Region Scale: Biogeography of Aphodiini Dung Beetles (Coleoptera, Scarabaeidae) Based on Species Geographic and Taxonomic Data

Taxonomic Studies on Dung Beetles (coleoptera: Scarabaeidae, Geotrupidae, Hybosoridae) of Chhattisgarh, India

The study presents taxonomic account of 52 species of dung beetles belonging to 22 genera, 12 tribes, 04 subtribes, 05 subfamilies and 03 families viz. Scarabaeidae, Geotrupidae and Hybosoridae from Chhattisgarh. Interactive identification keys to the subfamilies, tribes, genera and species were prepared by studying thoroughly the morphological characters of all the dung beetles specimens colle...
