Aspectos biologicos de Canthon uturatus (Germar, 1813) e Canthidium (Canthidium) Megathopoides boucomont, 1928 (Coleoptera, Scarabaeidae)
We studied food relocation habits and nidification behavior for the dung beetles Canthon lituratus (Germar) and Canthidium (Canthidium) megathopoides Boucomont. Observations were done in dung pads of Guzerá cattle present in open pasture in Selvíria, Mato Grosso do Sul State, Brazil. In Canthon Htur...

| description | We studied food relocation habits and nidification behavior for the dung beetles Canthon lituratus (Germar) and Canthidium (Canthidium) megathopoides Boucomont. Observations were done in dung pads of Guzerá cattle present in open pasture in Selvíria, Mato Grosso do Sul State, Brazil. In Canthon Hturatus, a telecoprid species, males and females alone, as well as couples were observad foriniiig riunq balls. Intia-specific competition for the ball was observad. Once the ball was made, the C. Hturatus rnale clinibed on top of it and attracted a female, probably by releasing a pheromone. After the pair was established. botfi lolled the ball, after which mating occurred, on the soil surface. After mating, the ball was lolled for an additional distance, before being buried; males could follow female after mating or not The ball was then buried by the female; if the male was present, he placed himself on top of the ball while the female was burying ¡t. Diameter and distance in which the ball was rolled, besides time of mating, are provided. Em Canthidium (Canthidium) megathopoides, a paracoprid species, niales and females alone took portions of dung and pulled them to a oertain distance, aftei which the ga'ilery was büilt and provided with the dung fragmenta. No intra or inter-specilic competition for the balls was observed. The pair was probably formed after the gallery was dug. Gallery shape and dimensions, as well as distances the dung was removed, are given. |

Estudou-se aspectos de hábito de relocacáo de alimento e nidificacáo paia as espécies de besouros coprófagos Canthon hturatus (Germar) e Canthidium (Canihidium) megathopoides Boucomont. As observacoes foram feitas em Selvíria/MS, Brasil, em massas fecais de bovinos Guzetá, depositadas em pasto. Em Canthon hturatus, espécie telecoprídea, machos e fémeas sozinhos, bem como casais, elaboraram esferas fecais, tendo havido competicao intra-específica por estas. Urna vez formada a esfera, o macho de C. Hturatus atraía fémeas, provavelmente pela liberacao de feromónio. Formado o casal, ambos rolavam a esfera, após o que ocorria cópula, á superficie do solo. Após a cópula, a esfera era rolada por urna distancia adicional, antes de ser enterrada, sendo a fémea acompanhada ou nao pelo macho. A esfera era enterrada pela fémea, e guando o macho estava presente, o mesmo postava-se sobre a esfera. Medidas de diámetro e distancias roladas pelas esferas sao fornecidas. Em Canthidium {Canthidium) megathopoides, espécie paracoprídea, machos e fémeas sozinhos retiravam porcoes de massas fecais e as empurravam a urna certa distancia, sendo entáo a a galeria construida e próvida. Nao se obseivou competicao intra- ou ínter-especifica. O casal era formado provavelmente no período posterior ao da formacáo da galena. Formato e dimensoes das galerías sao apresentados, bem como distáncias em que as massas fecais eram empurradas.
