The genome sequence of Trichoplusia ni enables the use of this widespread lepidopteran pest as a model for both the study of small RNA pathways and insecticide resistance.

In moths, male receptors tuned to type I female pheromones may not have a monophyletic origin.

CenH3, the defining component of centromeres in almost all eukaryotes, was independently lost in four insect lineages that transitioned from monocentricity to holocentricity.

Novel virus-host systems yield insights into how Lepidopterans (moths and butterflies) combat RNA virus infection and reveal that poxvirus A51R proteins can suppress the host's immune system and stabilize microtubules in host cells.

A gradual, step-wise, physiological/molecular response of eyespot size to temperature is a likely adaptation to seasonal variation experienced in the habitat of Bicyclusanynana butterflies.

A mimetic complex composed of at least 140 species of ants, wasps, spiders, true bugs and treehoppers, all with conspicuous golden bodies, has been discovered.

Genetic manipulation demonstrates the costs and benefits of detoxifying glucosinolate plant defenses in a pest insect and its predator.

Evolutionary reconstruction of the ecdysis pathway shows that its major elements are present in the majority of metazoans, providing evidence that they originated much earlier than currently assumed.

A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.

Rarity metrics reveal pervasive negative impacts of agricultural land use on soil invertebrate communities, whereas widely-used richness and diversity metrics underestimate the magnitude of these impacts.
