Thomas Say
Thomas Say (June 27, 1787 – October 10, 1834) was an American entomologist, conchologist, and herpetologist. His studies of insects and shells, numerous contributions to scientific journals, and scientific expeditions to Florida, Georgia, the Rocky Mountains, Mexico, and elsewhere made him an internationally known naturalist. Say has been called the father of American descriptive entomology and American conchology. He served as librarian for the Academy of Natural Sciences of Philadelphia, curator at the American Philosophical Society (elected in 1817), and professor of natural history at the University of Pennsylvania. Early life and education Born in Philadelphia into a prominent Quaker family, Thomas Say was the great-grandson of John Bartram, and the great-nephew of William Bartram. His father, Dr. Benjamin Say, was brother-in-law to another Bartram son, Moses Bartram. The Say family had a house, "The Cliffs" at Gray's Ferry, adjoining the Bartram family farms in King ...

Dung Beetle
Dung beetles are beetles that feed on feces. Some species of dung beetles can bury dung 250 times their own mass in one night. Many dung beetles, known as ''rollers'', roll dung into round balls, which are used as a food source or breeding chambers. Others, known as ''tunnelers'', bury the dung wherever they find it. A third group, the ''dwellers'', neither roll nor burrow: they simply live in dung. They are often attracted by the feces collected by burrowing owls. There are dung beetle species of various colors and sizes, and some functional traits such as body mass (or biomass) and leg length can have high levels of variability. All the species belong to the superfamily Scarabaeoidea, most of them to the subfamilies Scarabaeinae and Aphodiinae of the family Scarabaeidae (scarab beetles). As most species of Scarabaeinae feed exclusively on feces, that subfamily is often dubbed ''true dung beetles''. There are dung-feeding beetles which belong to other families, such as the Geo ...

Scarabaeidae
The family Scarabaeidae, as currently defined, consists of over 30,000 species of beetles worldwide; they are often called scarabs or scarab beetles. The classification of this family has undergone significant change in recent years. Several subfamilies have been elevated to family rank (e.g., Bolboceratidae, Geotrupidae, Glaresidae, Glaphyridae, Hybosoridae, Ochodaeidae, and Pleocomidae), and some reduced to lower ranks. The subfamilies listed in this article are in accordance with those in Bouchard (2011). Description Scarabs are stout-bodied beetles, many with bright metallic colours, measuring between . They have distinctive, clubbed antenna (biology), antennae composed of plates called lamella (zoology), lamellae that can be compressed into a ball or fanned out like leaves to sense odours. Many species are fossorial, with legs adapted for digging. In some groups males (and sometimes females) have prominent horns on the head and/or pronotum to fight over mates or re ...

Deltochilini
Deltochilini (or Canthonini) is a tribe of scarab beetles, in the dung beetle subfamily ( Scarabaeinae). Members of this group vary widely in size (2–33 mm long) and shape, but were thought to be derived from an ancient ball-rolling lineage. The outer edges of the front tibiae have less than four teeth. The grouping based on these characteristics has, however, been found to have little phylogenetic validity, and the placement of several genera in the tribe is likely to change. Taxonomy There has been some controversy regarding the valid name for this tribe. Deltochilini is the senior name, and has precedence under the ICZN, but in 2006, Smith suggested that the name Canthonini, though junior, might be preserved under Code Article 35.5, which can be used to preserve junior names if they are higher in taxonomic rank than the senior names of constituent taxa.Smith, A.B.T.
