The development of museomics represents a major paradigm shift in the use of natural history collection specimens for systematics and evolutionary biology. New approaches in this field allow the sequencing of hundreds to thousands of loci from across the genome using historical DNA. HyRAD-X, a recently introduced capture method using bench-top designed probes, has proved very efficient to recover genomic-scale datasets using natural history collection specimens. Using this technique, we infer at both the intra- and interspecific levels, the most robust phylogeny of Arcifera to date, an ecologically and morphologically diverse clade ofCarabusgiant ground beetles. We successfully generated a genomic dataset of up to 1965 HyRAD-X loci for all described species, permitting to infer a robust dated phylogenomic tree of this clade. Our species delimitation and population genomic analyses suggest that the current classification in Arcifera is in line with its evolutionary history. Our results suggest an origin of Arcifera in the late Oligocene followed by speciation events during the warm mid-Miocene unlinked to Pleistocene glaciations. The dynamic paleogeographic history of the Palearctic region likely contributed to the diversification of this lineage with a relatively ancient colonization of the proto-Alps followed byin situspeciation where most species of Arcifera are currently found sometimes syntopically likely as a result of post-glaciations secondary contacts.

1. Genomic data are not yet widely used in insect conservation practice. Here, with a focus on butterflies, we aim to identify the strengths, limitations and remaining gaps between the fields of population genomics and insect conservation management.Based on a literature search complemented with expert opinion, we discuss avenues for translating research into practice.2. We found that current genomic methodologies available for insect management enhance the assessment of cryptic diversity and facilitate the inference of historical population trends (temporal monitoring) by using even degraded material from historical collections.3. Discovering and tracking adaptive genetic variation linked to increased survival and fitness is a relatively young research field, but we highlight it as a promising tool in future insect management actions.4. We highlight recent case studies where population genomics have guided butterfly conservation. One conclusion from our advice from our non-exhaustive survey of expert opinion is to establish meaningful partnerships between researchers and practitioners, starting at the stage of project planning. Genomics is an informative tool for securing legal protection of unique populations and may offer guidance in future conservation translocations and captive breeding programmes. 5. Although insect conservation usually targets habitats, genomic guidance focusing on populations of flagship and umbrella taxa is a straightforward path to connect species-specific and habitat conservation initiatives. We conclude that there is urgency in reporting insect conservation actions guided by genomic data, both successful and unsuccessful. This will lead to constructive feedback between fields and the establishment of standardised methodologies.
