Insects as Food
TLDR
This chapter is a step in the direction of creating awareness of how entomophagy is essential and needs to be encouraged, a realization that is increasingly becoming imminent.
The immature stages, larval food plants and biology of Neotropical mistletoe butterflies (Lepidoptera: Pieridae). II. The Catasticta group (Pierini: Aporiina)
TLDR
The morphology and biology of the immature stages of the Catasticta group are compared with other members of the Aporiina, particularly those of Delias, Aporia and the more distantly related Mylothris, and comments made on their systematic relationships.
Phylogeny and historical biogeography of the subtribe Aporiina (Lepidoptera: Pieridae): implications for the origin of Australian butterflies
TLDR
It is shown that an origin of the Aporiina in either southern Gondwana or Laurasia is equally parsimonious, and that dispersal has played a major role in shaping the underlying phylogenetic pattern.
Evolution of larval host plant associations and adaptive radiation in pierid butterflies
TLDR
In the Pierinae, a striking association between host plant, larval and adult behaviour, adult phenotype, and mimicry calls for further research into possible relationships between host specialization, plant chemistry and butterfly palatability.
SEXUAL DIMORPHISM IN EYE MORPHOLOGY IN EUCHElRA SOCIALIS
We examined the magnitude of sexual dimorphism in the eyes of madrone butterflies, Eucheira sociaZis (Pieridae). Via microscopic examination of the cornea, we determined the eye surface area, facet
Pine processionary moth (Thaumetopoea pityocampa) and great tit (Parus major) in Portugal
TLDR
The earliest breeding start for this species was recorded in the study area, indicating that Portuguese coastal pines provide good breeding conditions earlier than in other areas of Europe and North Africa.
Trail Marking by the Larva of the Madrone Butterfly Eucheira socialis and the Role of the Trail Pheromone in Communal Foraging Behavior
TLDR
The study shows that Eucheira employs a relatively unsophisticated system of trail-based communication and does not recruit to food, which appears to represent an early stage in the evolution of cooperative foraging that is derived from, and motivationally linked to, conflict behavior.
Social life-styles in caterpillars: Behavioral mechanisms and ecological consequences
TLDR
Investigation of thermal characteristics of aggregations of social, tent building caterpillars of the small eggar moth Eriogaster lanestris shows that metabolic heat production sufficiently explains this effect, and suggests aggregating in the tent may confer selective advantages under overcast weather or at night, when behavioral thermoregulation through basking is not possible.
Plasticity in foraging patterns of larval colonies of the small Eggar moth, Eriogaster lanestris (Lepidoptera: Lasiocampidae)
TLDR
E. lanestris is the first lepidopteran species with CPF social caterpillars reported to show a plastic, but nevertheless strictly synchronized foraging pattern, which is able to optimize their food intake and enhance growth during periods of thermally favourable conditions while minimizing their exposure to natural enemies.

Eastern tent caterpillars that are successful foragers deposit trails as they return to the tent that are more attractive than the exploratory trails of the unfed larvae. The trails of these fed
