However, most aphids found were oligophagous or polyphagous, which disagrees with a previous study in Sao Carlos, Brazil (Peronti & Sousa da Silva, 2002), where monophagy prevailed as the most common pattern of host specificity.
In order to emphasize patterns of host utilization, only oligophagous beetles were included as defined above and shown in Table III.

Thematically similar phenomena are described by Topp (for an oligophagous chrysomelid, which uses the phenolglycoside defensive compounds of its host, willows, to repel insectivorous birds) and Tomaschko (pycnogonids, a phylogenetically ancient lineage of marine arthropods, use ecdysteroi ds partially gathered from food for defense against predator crustaceans).
In 1920, Brues observed that insects were instinctively polyphagous, oligophagous or monophagous and began to address many of the questions still central to the study of plant-herbivore interactions.
Alternatively it may be because in the grasshoppers we studied, there is no progressive feeding specialization during succession: diet is rather uniform, ranging from oligophagous (mainly Poaceae) or polyphagous (Dicots and Poaceae) (El Ghadraoui et al.

Individual caterpillars in several species of oligophagous sphingids not only take on the color of the different host foliage, but also have been shown to select a background to match their acquired colors (Poulton 1885, Grayson and Edmunds 1989).
The goldenrod ball gallmaker is a narrowly oligophagous herbivore that occurs primarily on Solidago altissima over most of its range (Abrahamson et al.
In comparison, some oligophagous insects seem more susceptible to dietary ecdysteroids, such as Pectinophora gossypiella (Saunders) (Gelechiidae) (Kubo et al.
Hokkannen and Pimentel (1984, 1989) marshal literature data to show that many, perhaps most, truly effective biological-control programs involve new associations of host and enemy, and often they entail new-host use by species previously considered monophagous or oligophagous.
Also, all three genera are fed upon by the larvae of the same (Dalechampia and Tragia) or related (Plukenetia) genera of oligophagous nymphalid butterflies, further supporting their close relationship (Armbruster and Mziray 1987; De Vries 1987; Otero 1990; Armbruster 1994).
