  author={Nancy E. Stamp and M Deane Bowers},
We examined the foraging patterns of two species of caterpillar (Junonia coenia: Nymphalidae and Spilosoma congrua: Arctiidae) that contrast in feeding specialization and crypticity on plantain (Plantago lanceolata) in the absence and presence of two different insect predators [stinkbugs, Podisus maculiventris (Pentatomidae) and wasps, Polistes fuscatus (Vespidae)]. Junonia larvae were quite apparent to human observers, feeding on upper leaf surfaces during daylight, whereas Spilosoma larvae… 
Resource-mediated impact of spider predation risk on performance in the grasshopper Ageneotettix deorum (Orthoptera: Acrididae)
Increased resource quality can clearly moderate the negative life history responses caused by the behavioral modification of grasshoppers when exposed to spider predation risk, a compensatory response.
Do Enemies of Herbivores Influence Plant Growth and Chemistry? Evidence from a Seminatural Experiment
The lack of effect by predators seems to reflect the relatively large variation in iridoid glycoside concentration among leaf ages, and the herbivores ability to respond to that variation, such that the difference in iriridoid Glycoside concentrations in the plant genotypes was less important.
Predator-Induced Plasticity on Warning Signal and Larval Life-History Traits of the Aposematic Wood Tiger Moth, Arctia plantaginis
Predator-induced plasticity in life-history and antipredator traits during the larval period has been extensively studied in organisms with complex life-histories. However, it is unclear whether
Competitive interactions between an exotic and a native ladybeetle: a field cage study
The mortality and weight gain of larvae of both species in field cages that enclosed one or both species with corn plants containing high or low aphid numbers and the spatial distribution of C. maculata over the plants differed between single‐species and two‐species treatments in a manner that suggested that this species avoided interactions with H. axyridis.
Trichogramma pretiosum parasitism and dispersal capacity: a basis for developing biological control programs for soybean caterpillars
Evaluating the parasitism (%) in eggs of Anticarsia gemmatalis and Pseudoplusia includens after the release of different densities of the egg parasitoid Trichogramma pretiosum concluded that for a successful biological control program of lepidopteran pests using T. Pretiosum in soybean fields, a density of 25.6 parasitoids per host egg, divided into 117 sites per hectare should be used.
Long Frontal Projections Help Battus philenor (Lepidoptera: Papilionidae) Larvae Find Host Plants
These findings suggest that the frontal projections and associated mechanosensillae act as vertical object detectors to obtain tactile information that, together with visual information from lateral ocelli and presumably chemical information from antennae and mouthparts, help larvae to find host plants.
Investigating the Relationship Between Dietary Specialization of Caterpillars and Their Risk of Ant Predation in a Forest Community
The risk of predation by ants is quantified for a community of caterpillar species that employ several putative anti-predator traits that may be constrained by dietary specialization and their correlation with diet breadth in a temperate forest.
Chemical and structural effects of invasive plants on herbivore–parasitoid/predator interactions in native communities
It is suggested that some herbivores, and by association their parasitoids, may benefit from the establishment and spread of exotic plants because they increase the amount of available resources for them to exploit.


Foraging behavior of specialist and generalist caterpillars on plantain (Plantago lanceolata) altered by predatory stinkbugs
The stinkbugs reduced the survivorship of the specialist caterpillars but not that of the generalists, which reflects the differences in predatoravoidance behaviors of these species.
Relative susceptibility to predation of two species of caterpillar on plantain
It is indicated that Spilosoma caterpillars, by way of cryptic and escape behaviors, can be less susceptible to insect predators than Junonia caterpillar.
Direct and indirect effects of predatory wasps (Polistes sp.: Vespidae) on gregarious caterpillars (Hemileuca lucina: Saturniidae)
It is suggested that wasps, in addition to killing caterpillars, indirectly affect larval fitness by slowing larval growth, at least in part by forcing larvae into cooler microhabitats where leaves are of lower quality.

The efficiency of both defensive strategies is compared and discussed, taking into account these particular field distributions, predation and some parasitism factors, and the chemical defences of both species.

Larvae of the buckeye,Junonia coenia (Nymphalidae) feed primarily on plants in four families: Scrophulariaceae, Plantaginaceae, Verbenaceae, and Acanthaceae. These plant families have in common the
Comparative Efficacy of Four Insect Predators of the Bollworm and Tobacco Budworm
Under expanded searching requirements, C. carnea larvae were the most efficient of the immature stages of predators on Heliothis eggs and 1st instars while G. punctipes was the most effective predators on 1st stage larvae.
Predator avoidance, microhabitat shift, and risk-sensitive foraging in larval dragonflies
Evidence indicates that vulnerability probably varies widely among species and even among instars within species, and suggests that spatial distributions of relatively vulnerable species may be limited by their inability to avoid predation.
Fate of iridoid glycosides in different life stages of the Buckeye,Junonia coenia (Lepidoptera: Nymphalidae)
Feeding experiments suggested that this reduction in actively feeding larvae was due to the metabolism of iridoid glycosides, and calculation of irids consumption and utilization indices showed that larvae fed artificial diets consumed, digested, and sequestered aucubin and catalpol in similar ways.
Biological Studies of Polistes in North Carolina (Hymenoptera: Vespidae)
Though nest founding by overwintering queens began in early April, most nests were established in late April and early May, and diurnal and seasonal variations in the number of returners with various materials were influenced by temperature.
Indirect effect on survivorship of caterpillars due to presence of invertebrate predators
Differences in the indirect effect are discussed in particular relative to the behavior of predators and prey, ratio of predator to prey sizes, and morphology of the hostplants.
