Geniates barbatus - Yellow Beetle / Besouro-Amarelo (Kirby, 1818) Coleoptera: Polyphaga: Scarabaeiformia: Scarabaeoidea: Scarabaeidae: Rutelinae: Geniatini<br />
<br />
These beetles are found from northern Panama to central Chile and southern Argentina; this includes Brazil, where the subject portrayed was found. They are members of the order Coleoptera, suborder Polyphaga, infraorder Scarabeiformia, superfamily Scarabaeoidea, family Scarabaeidae, subfamily Rutelinae and tribe Geniatini.<br />
<br />
The feeding habits of immature Geniates barbatus are unknown, but it is speculated that they feed on the roots of grasses (Poaceae) and other plants - as they are always found underground when in the larval phase - until entering the pupa stage and emerging from the ground as an adult, proceeding to mate and to lay the eggs underground.<br />
<br />
The adult&#039;s hosts include Eucalyptus robustus (Sm.), E. tereticornis (Sm.) (Myrtaceae), and Cammellia sinensis (Kuntze) (Ternstroemiaceae, otherwise known popularly as &quot;tea&quot;). The adult was also seen defoliating other plants, like: Anacardium occidentale (L.) (Anacardiaceae) (cashew, &quot;cajueiro&quot;), Cocos nucifera (L.) (Arecaceae) (coconut palm, &quot;coqueiro&quot;), Eugenia pitanga ((O. Berg) Nied.) (Myrtaceae) (Surinam cherry, &quot;pitangueira&quot;), Mangifera indica (L.) (Anacardiaceae) (mango tree, &quot;mangueira&quot;), Rosa spp. (Rosaceae), Psidium guajava (L.) (Myrtaceae) (guava tree, &quot;goiabeira&quot;) and Terminalia sp. (Combretaceae) (Anjos &amp; Majer, 2003; Costa Lima, 1953; Silva et al., 1968).<br />
<br />
The larvae of Geniatini seem to be more similar to Anoplognathini than to Rutelini or Anomalini.<br />
<br />
Their habitats are gardens, pastures, forests, fields, weedy places and woods; they are mostly found buried underground where there are Poaceae growing.<br />

The adult's hosts include Eucalyptus robustus (Sm.), E. tereticornis (Sm.) (Myrtaceae), and Cammellia sinensis (Kuntze) (Ternstroemiaceae, otherwise known popularly as "tea"). The adult was also seen defoliating other plants, like: Anacardium occidentale (L.) (Anacardiaceae) (cashew, "cajueiro"), Cocos nucifera (L.)
