Highlights•Technical advances are producing bigger and denser Drosophila melanogaster
connectomes.•Mapping connectomics to other data types is a challenging but crucial …

Long-lasting internal arousal states motivate and pattern ongoing behaviour, enabling the
temporary emergence of innate behavioural programs that serve the needs of an animal …

Behavioral sex differences primarily derive from the sexually dimorphic organization of
neural circuits that direct the behavior. In Drosophila melanogaster, the sex-determination …

Sex differences in whole-body fat storage exist in many species. For example, Drosophila
females store more fat than males. Yet, the mechanisms underlying this sex difference in fat …

Abstract Background Neuroscience research in Drosophila is benefiting from large-scale
connectomics efforts using electron microscopy (EM) to reveal all the neurons in a brain and …

Precise, repeatable genetic access to specific neurons via GAL4/UAS and related methods
is a key advantage of Drosophila neuroscience. Neuronal targeting is typically documented …

Courtship has evolved to achieve reproductive success in animal species. However,
whether courtship itself has a positive value remains unclear. In the present work, we report …

Colonization of a novel ecological niche can require, or be driven by, evolution of an
animal's behaviors promoting their reproductive success. We investigated the evolution and …

Sequenced behaviours, including locomotion, reaching and vocalization, are patterned
differently in different contexts, enabling animals to adjust to their environments. How …

Mated females reallocate resources to offspring production, causing changes to nutritional
requirements and challenges to energy homeostasis. Although observed across species …
