Local outbreaks of Operophtera brumata and Operophtera fagata cannot be explained by low vulnerability to pupal predation [PDF]
One of the unresolved questions in studies on population dynamics of forest Lepidoptera is why some populations at times reach outbreak densities, whereas others never do.

Abstract Lepidoptera have long been known to feed on the tears of vertebrates as a presumed source of minerals or nutrients. While this unusual behavior has been observed in a variety of species, only a single previous record has been documented outside of the tropics. Here, we present the first documentation of moths visiting the eyes of a bull moose (

Phylogenetic relationships of selected European Ennominae (Lepidoptera: Geometridae)
This study reports the results of a molecular phylogenetic analysis of thirty three species of Ennominae (Lepidoptera: Geometridae). The aim of this analysis was to determine the phylogenetic affinities of 13 European species not previously studied using

Multi-objective optimization shapes ecological variation [PDF]
Ecological systems contain a huge amount of quantitative variation between and within species and locations, which makes it difficult to obtain unambiguous verification of theoretical predictions.

Abstract The large genus Campylocheta Rondani, 1859, comprising 48 species, occurs in all major biogeographical regions of the world, except Antarctica. Homohypochaeta Townsend, 1927 and Hypochaetopsis Townsend, 1915 are two Neotropical genera similar to Campylocheta, with only two and one species respectively.

In this study we examine the relationship between the Lunar Phases and the efficiency of light traps in catching winter moth (Operophthera brumata Linnaeus, 1758).

The magnitude of cryptic insect diversity in one tropical rainforest
We detected 214 cryptic species out of a total of 2006 species (10.6%) examined from 22 focal insect taxa in 1500 ha tropical rainforest in Panama. The percentage of cryptic species varied greatly among assemblages (0%–19%), with half of the assemblages devoid of cryptic species and the highest proportions of cryptics in Pieridae and Formicidae ...

Responses of generalist invertebrate predators to pupal densities of autumnal and winter moths under field conditions [PDF]
1. Generalist natural enemies are usually not considered as being capable of causing population cycles in forest insects, but they may influence the population dynamics of their prey in the low density cycle phase when specialist enemies are largely ...

Reversed impacts by specialist parasitoids and generalist predators may explain a phase lag in moth cycles : a novel hypothesis and preliminary field tests [PDF]
Among cyclic populations of herbivores, inter-specific temporal synchrony has been attributed to both climatic factors and trophic interactions. In northern Europe, winter and autumnal moths undergo regular 9–11 year population cycles.

Invasion of winter moth in New England: Effects of defoliation and site quality on tree mortality. [PDF]
Widespread and prolonged defoliation by the European winter moth, Operophtera brumata L., has occurred in forests of eastern Massachusetts for more than a decade and populations of winter moth continue to invade new areas of New England.
