“…We focused on the terrestrial heteropterans in the suborders Cimicomomorpha and Pentatomomorpha because they include large numbers of herbivores, omnivores, and predators, and because strict herbivory, omnivory, and strict predation have evolved independently multiple times within these groups (Cobben 1979, Sweet 1979, Schuh 1986, Schuh and Slater 1995, Alomar and Wiedenmann 1996.

“…These insects represent a unique blend of morphological, physiological, and behavioral adaptations found in their predaceous and herbivorous relatives. Omnivorous heteropterans also have piercing-sucking mouthparts (stylets) with characteristics of both herbivorous heteropterans (smooth stylets to penetrate plants) and predaceous heteropterans (toothed or curved stylets for Manuscript (Faucheux 1975, Cobben 1979, Cohen 1996. In addition, many species of omnivorous heteropterans produce protein-digesting enzymes (proteinases and phospholipases) and plant-digesting enzymes (amylases and pectinases) whereas their strictly herbivorous and predaceous cousins produce only a subset (Baptist 1941, Goodchild 1966, Kahn and Ford 1967, Miles 1972, Varis et al 1983, Cohen 1990, 1996, Schaefer and Panizzi 2000, Wheeler 2001).…”

“…As a result, herbivorous insects are usually adapted to feed on a particular part of their host plant or plants (Janzen 1979, Kirk 1985. Some authors have hypothesized that seed and pollenfeeding herbivores may be preadapted to consume nitrogen-rich prey and, consequently, that lineages of seed or pollen-feeding herbivores will give rise to omnivores more frequently than lineages of foliagefeeding herbivores (Sweet 1979, Cobben 1979. Some authors have hypothesized that seed and pollenfeeding herbivores may be preadapted to consume nitrogen-rich prey and, consequently, that lineages of seed or pollen-feeding herbivores will give rise to omnivores more frequently than lineages of foliagefeeding herbivores (Sweet 1979, Cobben 1979.…”

“…In addition, the three feeding habits have evolved multiple times within this order, with herbivorous lineages giving rise to predators and predaceous lineages giving rise to herbivores (Cobben 1979, Sweet 1979, Schuh 1986, Schuh and Slater 1995, Coll 1998). Terrestrial heteropterans are an ideal group for studying the evolution of feeding habits because they have diverse feeding habits, contain many omnivorous species, have well-known biologies, and have relatively wellestablished taxonomic and evolutionary relationships.…”

Although omnivory is common and widespread across many animal taxa, the evolutionary origin of omnivory, the selective forces that promote or constrain omnivory, and the morphological, physiological, and behavioral hurdles that animals have to overcome to become omnivores have not been studied. The goal of this paper is to stimulate the development of ideas concerning the evolution of omnivory. We focus on the terrestrial lineages of the insect order Heteroptera and use published life history data and recent phylogenies to test two hypotheses concerning the evolutionary origin of feeding on both plants and prey: (1) that the propensity to feed on seeds and pollen is correlated with the evolution of omnivory, and (2) that broad host range (polyphagy) is correlated with the evolution of omnivory. In order to test these hypotheses, we mapped the plant part consumed and host plant range of insect species in two heteropteran suborders onto their respective phylogenies and used phylogenetically independent contrasts to test for correlations of these traits with omnivory. We found evidence that seed and pollen feeding and broad host ranges are correlated with the evolution of omnivory within both ancestrally herbivorous and ancestrally predaceous lineages of terrestrial heteropterans.

Biology and the environment are inextricably linked. Insects are intricately linked to their habitats as part of the ecosystem. In this study, scanning electron microscopy (SEM) observations showed two sensilla chaetica, several sensilla trichodea, and at least one sensilla basiconicum on the antennae of typhlocybine insects. There were no sensilla on the labrum; however, the surface morphology was different. There were more sensilla trichodea on the surface, mostly symmetrically distributed along the labial groove, and there was little difference in the structure of the stylet fascicle. The correlation between the sensilla number on the body surface of typhlocybine insects and environmental factors in the 3 study areas was as follows: Huajiang > Bijie > Shibing, which is consistent with the classification of rocky desertification grade; that is, the higher the rocky desertification grade, the greater the sensilla number on leafhoppers affected by the environment. The correlation between the number of leafhoppers and environmental factors in the 3 months was as follows: end of September > end of May > end of July, which was consistent with the changing temperature trends. The results of this study enrich our knowledge of the morphological characteristics of leafhoppers and explore the potential value of insect surface ultra‐morphology for use by humans.
