Scope
Aims, scope and focus
Fly is published by Landes Bioscience and is in Zone 4 of Biology in the CAS Journal Ranking (2025 upgraded edition). By OpenAlex counts of its recent articles, its largest topics are Neurobiology and Insect Physiology Research, Invertebrate Immune Response Mechanisms and Developmental Biology and Gene Regulation, together about 31.1% of its articles. Its main subfields are Molecular Biology. (generated from OpenAlex topic counts and CAS ranking data)
Aims & Scope: Fly is the first international peer-reviewed journal to focus on Drosophila research. Fly covers a broad range of biological sub-disciplines, ranging from developmental biology and organogenesis to sensory neurobiology, circadian rhythm and learning and memory, to sex determination, evolutionary biology and speciation. We strive to become the “to go” resource for every researcher working with Drosophila by providing a forum where the specific interests of the Drosophila community can be discussed. With the advance of molecular technologies that enable researchers to manipulate genes and their functions in many other organisms, Fly is now also publishing papers that use other insect model systems used to investigate important biological questions. Fly publishes articles under various categories, including Research Reports, Methods and Technical Advances, Reviews and Commentaries. In addition, Fly also features two unconventional types of contribution, Educational Resources and 'Extra View' articles. Educational Resources describe, review or present Drosophila-related materials used for the teaching of genetics, cell or developmental biology or other relevant topics at undergraduate or high-school level. 'Extra View' articles are generally solicited by Fly editors and provide authors of papers recently published elsewhere an opportunity to expand on their original findings and discuss the broader impact of their discovery. 'Extra View' authors may supplement their published observations with additional data not included in the original paper. All article types are peer-reviewed. Please note that Fly converted to a full Open Access journal from Volume 16 (2022).
