“…The form does not appear indicative of specialised diets such as carrion (Hybosoridae) or dung feeding (Scarabaeinae, Aphodiinae) and therefore a phytophagous or saprophagous /fungivorous diet would seem most likely. If dietary preference was shared with extant adult melolonthines, then a strictly phytophagous diet should be expected which could include leaves, flowers or young fruits (Ritcher 1958). According to Nel and Scholtz (1990), the forms of mouthparts of extant melolonthines can be divided into five groups of which the mandible of the Orapa specimen most closely resembles group 2.…”

A full description is given of the first scarabaeid beetle documented from the Mesozoic (Late Cretaceous) of Africa (Orapa, Botswana). Brief and partial descriptions of this beetle have appeared in two previous review papers of fossils from the Orapa Diamond Mine. This work represents an updated analysis and interpretation of the fossil based on character comparison and phylogenetic analysis. The new genus and species, Ceafornotensis archratiras, are described in Melolonthinae incertae sedis. Phylogenetic analysis suggests a sister group relationship with the tribe Phaenognathini (Melolonthinae incertae sedis). Although phytophagy in the adult beetle cannot be confirmed, it is proposed that angiosperms could have contributed to a proportion of its diet (larval or adult). This beetle may belong to a stem lineage of pleurostict scarabaeids which later experienced major radiation in response to widespread environmental changes brought about by continuing radiation of the angiosperms.

“…Our observations showed that H. elegans has a greater potential to be an important element of the saprophagous soil macrofauna than does P. herrmanni and S. nigrolineata. The former produces higher proportions of faeces/unit of live larval weight when it is feeding on soil alone, probably because Rutelinae are less phytophagous specialists than Melolonthinae (Ritcher 1958).…”

“…KEY WORDS: Ingest, compaction, white grub Scarabaeidae larvae have diverse feeding habits, feeding on carrion, dung, fresh or decomposing plant matter on or in the soil (Ritcher 1958). They constitute part of the soil-macrofauna worldwide, exploiting the rhizosphere of pastures and crops causing severe damage (Kuniata & Young 1992, Harari et al 2001, Oyafuso et al 2002, Potter & Held 2002.…”

-Larvae of Hylamorpha elegans (Burm.) and Phytoloema herrmanni Germ. feed on roots, although many Scarabaeidae species are able to feed and survive on soil without living roots. In this study we evaluated the potential of H. elegans and P. herrmanni to ingest soil by estimating the rate of soil egestion. In the laboratory, the rate of soil egestion was determined from gut content and gut transit time of 3 rd -instar larvae feeding on soil without roots. The soil egestion rate was 14-21 mg g

“…Ritcher (1966) refers to the larvae of some species of Rutelinae as feeding on the roots of different plant species, or on decaying wood, or in the soil in the vicinity of decaying wood. Following Ritcher (1958) the studied species belongs to the Sacarabaeidae group of decaying wood and living root feeders.…”
