Caterpillars of the spring brood of Nemoria arizonaria develop into mimics of the oak catkins upon which they feed. Caterpillars from the summer brood emerge after the catkins have fallen and they develop instead into mimics of oak twigs. This developmental polymorphism may be triggered by the concentration of defensive secondary compounds in the larval diet: all caterpillars raised on catkins, which are low in tannin, developed into catkin morphs; those raised on leaves, which are high in… Expand

Environmentally Induced Color Polymorphism in Caterpillars of Biston betulavia lognataria
A developmental color polymorphism occurs in the larvae of Biston betularia cognataria, the American subspecies of the peppered moth. These larvae derive protection from predators by resembling twigsExpand
Phenotypic plasticity and nutrition in a phytophagous insect: consequences of colonizing a new host
TLDR
The European rose-hip fruit fly Rhagoletis alternata (Diptera, Tephritidae) infests hips of Rosa species, which generates a considerable part of life-history diversity within a species and reinforce differences in the ecological context of the ancestral and new host. Expand
Diet-induced chemical phytomimesis by twig-like caterpillars of Biston robustum Butler (Lepidoptera: Geometridae)
TLDR
The chemical similarities between the caterpillars and the twigs were due to the digestion of host leaves, which indicates that this is a diet-induced adaptation. Expand
Feeding by lepidopteran larvae is dangerous: A review of caterpillars’ chemical, physiological, morphological, and behavioral defenses against natural enemies
TLDR
This review focuses on some of the best documented chemical, physiological, morphological, and behavioral characters which protect caterpillars from predators, parasitoids, and pathogens. Expand
Adaptive Growth Decisions in Butterflies
TLDR
Examples of growth decisions in butterfly larvae that can be viewed as adaptations for optimized growth performance are reviewed, which include sex-specific growth decisions that lead to protandry and sexual size dimorphism, fine-tuning of growth in response to photoperiod and temperature. Expand
Effect of light quality and larval diet on morph induction in the polymorphic caterpillar Nemoria arizonaria (Lepidoptera: Geometridae)
TLDR
Three experiments reported here independently varied larval diet and light characteristics to determine if light quality is involved in morph induction in the emerald mothNemoria arizonaria. Expand
Seasonal Polyphenism and Behavioral Variations of Ceroplastes glomeratus Peronti (Hemiptera: Coccidae)
TLDR
This work provides additional data on the morphological data of the species based on the microscopic and macroscopic characteristics of adult females and of first-instars of the two adult morphotypes of C. glomeratus. Expand
Foodplant effects on colour morphs of Eumorpha fasciata caterpillars (Lepidoptera: Sphingidae)
TLDR
Caterpillars of the hawkmothEumorpha fasciata are highly polymorphic for colour, with green, pink, and pink-and-yellow forms in the second through fourth instars, and green and multicoloured forms inthe fifth instar, and foodplant effects on larval colouration may be widespread in the family Sphingidae. Expand
Proximate and functional causes of polyphenism in an anuran tadpole
TLDR
This work examined the developmental and physiological bases underlying polyphenism in southern spadefoot toad tadpoles (Scaphiopus multiplicatus) and found that tadpole can change to the alternative morphology if their diet was switched. Expand
Folivorous larvae on flowers: do autumnal moths benefit from catkins of the mountain birch?
TLDR
It is suggested that young autumnal moth larvae actively move to male catkins, which provide a nutritional benefit and thus lead to a better performance compared with those feeding elsewhere, and another possible benefit for young larvae choosing the catkins instead of leaves may involve predator or parasitoid avoidance.

Diet-Induced Head Allometry Among Foliage-Chewing Insects and Its Importance for Graminivores
TLDR
Muscular effort increases muscular development in an insect, which in turn has a dramatic morphogenetic effect on head size, which has a direct effect on the ability of the insects to ingest hard foods rapidly: larger heads are adaptive for dealing with hard grasses. Expand
Determination of wing length and diapause in water-striders (gerris fabr., heteroptera).
TLDR
A new, tentative hypothesis is presented to explain both the laboratory experiments and the alary morphs found in different European populations of Gerris species, which suggests wing length is controlled by a photoperiodic switch, which is more or less adjusted by temperature. Expand
SEASONAL CHANGES IN OAK LEAF TANNINS AND NUTRIENTS AS A CAUSE OF SPRING FEEDING BY WINTER MOTH CATERPILLARS
TLDR
The content of oak leaf tannins, which inhibit the growth of winter moth larvae, increases during the summer and may render leaves less suitable for insect growth by further reducing the availability of nitrogen and perhaps also by influencing leaf palatability. Expand
Associations of Plants and Insects in Deciduous Forest
TLDR
A weighting factor for cluster analysis is introduced that weights a character (in this case the density of an insect species on a plant) in proportion to its deviation from the norm. Expand
Soldier determination in ants: new role for juvenile hormone.
TLDR
Control of worker dimorphism seems to be accomplished through control of timing of metamorphosis in the ant Pheidole bicarinata. Expand
Effects of crowding and host plant nutrition on a wing-dimorphic planthopper
TLDR
Body length exhibited a significant crowding x plant nutrition interaction; crowding had a greater reducing effect on body length if planthoppers were raised on marginal-quality hosts than on nutritionally superior hosts. Expand
Heritable divergence of Rhagoletis pomonella host races by seasonal asynchrony
TLDR
Heritable divergence in seasonal emergence of R. pomonella flies collected from sympatric populations on three host plant species in Illinois, in the United States is reported. Expand
On the Evolution of Host Specificity in Phytophagous Arthropods
We argue that generalist natural enemies of herbivorous insects provide a major selection pressure for restricted host plant range. The significance of plant chemistry is discussed in terms ofExpand
Genetic differentiation between sympatric host races of the apple maggot fly Rhagoletis pomonella
TLDR
The result confirms that hawthorn and apple flies represent partially reproductively isolated 'host races' and is consistent with a sympatric mode of divergence for these flies. Expand
