PMC Copyright notice PMCID: PMC13080333  PMID: 41994310 Version Changes Revised. Amendments from Version 1 Version 2 of this data note includes a full table giving the assembly metrics against the Earth BioGenome Project benchmarks (Table 3). We have corrected the Merqury.FK results using a new version of the software. We have added a sentence to the abstract to state that this assembly was generated as part of the Darwin Tree of Life Project. Abstract We present a genome assembly from an individual male Lampropteryx suffumata (the Water Carpet; Arthropoda; Insecta; Lepidoptera; Geometridae). The genome sequence is 581.6 megabases in span. Most of the assembly is scaffolded into 31 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 16.48 kilobases in length. Gene annotation of this assembly on Ensembl identified 18,663 protein coding genes. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.

Background Many species of insect are found widely across the Palaearctic realm from Europe to Asia, but relatively few have distributions that also extend to North America. Some exceptions include highly migratory species and those transported by human activity. A land connection existed until around five million years ago, the Bering land bridge, and until the land connection was lost there was some dispersal of species in each direction ( Gladenkov et al. , 2002 ; Jiang et al. , 2019 ). The Water Carpet Lampropteryx suffumata is a moth in the family Geometridae now known to exist on both sides of the Bering Strait. In Eurasia, the species is found commonly in northern and central Europe with the largest numbers of records from Britain, Scandinavia and Austria; there are scattered records ranging from Ireland and France in the west across to the far east of Russia, including Khabarovsk Krai and the Kamchatka peninsula, and on the Japanese island of Hokkaido ( Beljaev & Vasilenko, 2002 ; Beljaev et al. , 2022 ). In 2000 eight specimens of L. suffumata were recorded from Alaska, and in 2008 several Canadian specimens in museum collections were retrospectively identified as L. suffumata by DNA barcoding, including a historical specimen dating from 1919 ( Choi, 2000 ; Dewaard et al. , 2008 ). There is no suggestion that these North American individuals were accidentally introduced. Hence, the longitudinal range of L. suffumata extends from the Dingle Peninsula, Ireland, eastward across Eurasia and the Bering Strait to reach Alberta, Canada. Like most ‘carpet’ moths, named for their resemblance to the intricate patterns on woven carpets, the Water Carpet rests with its wings flat against the surface in a delta shape. The forewings are silvery-grey with a deeply indented brown cross-band outlined in white. In Britain and Ireland, the moth is on the wing from March to May, with the emergence time having moved earlier in the year since the 1970s ( Randle et al. , 2019 ). The species is most commonly encountered in damp woodland, moorland and fens, where the larvae feed on cleavers ( Galium aparine ) and other Galium species; the pupal stage overwinters ( South, 1961 ; Waring et al. , 2017 ). The complete genome sequence of Lampropteryx suffumata was determined as part of the Darwin Tree of Life project. The assembled genome will facilitate studies into the biogeography and population genetics of this widespread species and contribute to the growing set of resources for studying insect ecology and evolution. This assembly is the only publicly available genome for the genus Lampropteryx as of February 2026, based on data obtained via NCBI Datasets ( O’Leary et al. , 2024 ). Genome sequence report The genome was sequenced from one male Lampropteryx suffumata ( Figure 1 ) collected from Wytham Woods, Oxfordshire, UK (51.77, –1.34). A total of 39-fold coverage in Pacific Biosciences single-molecule HiFi long was generated. Primary assembly contigs were scaffolded with chromosome conformation Hi-C data. Manual assembly curation corrected 31 missing joins or mis-joins and removed 16 haplotypic duplications, reducing the assembly length by 1.99 % and the scaffold number by 11.86%, and increasing the scaffold N50 by 1.22%. Figure 1. Photograph of the Lampropteryx suffumata (ilLamSuff1) specimen used for genome sequencing. Open in a new tab The final assembly has a total length of 581.6 Mb in 51 sequence scaffolds with a scaffold N50 of 20.0 Mb ( Table 1 ). Most (99.81%) of the assembly sequence was assigned to 31 chromosomal-level scaffolds, representing 30 autosomes and the Z sex chromosome. Chromosome-scale scaffolds confirmed by the Hi-C data are named in order of size ( Figure 2 – Figure 5 ; Table 2 ). The Z chromosome was identified based on synteny with Eulithis prunata (GCA_918843925.1) ( Boyes & Holland, 2023 ). While not fully phased, the assembly deposited is of one haplotype. Contigs corresponding to the second haplotype have also been deposited. The mitochondrial genome was also assembled and can be found as a contig within the multifasta file of the genome submission.

Genome annotation report The Lampropteryx suffumata genome assembly (GCA_948098915.1) was annotated by Ensembl at the European Bioinformatics Institute (EBI). This annotation includes 18 828 transcribed mRNAs from 18 663 protein-coding genes. The average transcript length is 8 213.15 bp, with an average of 5.39 exons per transcript. Further details of this annotation are available from the Ensembl annotation page . Methods Sample acquisition and nucleic acid extraction The specimen used for genome sequencing was a male Lampropteryx suffumata (specimen ID Ox001102 , ilLamSuff1) was collected from Wytham Woods, Oxfordshire (biological vice-county Berkshire), UK (latitude 51.77, longitude –1.34) on 2021-03-31 using a light trap. The specimen was collected and identified by Douglas Boyes (University of Oxford), and was snap-frozen on dry ice. The specimen was prepared for DNA extraction at the Tree of Life laboratory, Wellcome Sanger Institute (WSI). The ilLamSuff1 sample was weighed and dissected on dry ice with tissue set aside for Hi-C sequencing. Thorax tissue was disrupted using a Nippi Powermasher fitted with a BioMasher pestle. DNA was extracted at the WSI Scientific Operations core using the Qiagen MagAttract HMW DNA kit, according to the manufacturer’s instructions. RNA was extracted from abdomen tissue of ilLamSuff1 in the Tree of Life Laboratory at the WSI using TRIzol, according to the manufacturer’s instructions. RNA was then eluted in 50 μl RNAse-free water and its concentration assessed using a Nanodrop spectrophotometer and Qubit Fluorometer using the Qubit RNA Broad-Range (BR) Assay kit. Analysis of the integrity of the RNA was done using Agilent RNA 6000 Pico Kit and Eukaryotic Total RNA assay. Protocols for high molecular weight (HMW) DNA extraction developed at the Wellcome Sanger Institute (WSI) Tree of Life Core Laboratory are available on protocols.io ( Howard et al. , 2025 ). Sequencing Pacific Biosciences HiFi circular consensus DNA sequencing libraries were constructed according to the manufacturers’ instructions. Poly(A) RNA-Seq libraries were constructed using the NEB Ultra II RNA Library Prep kit. DNA and RNA sequencing were performed by the Scientific Operations core at the WSI on Pacific Biosciences SEQUEL II (HiFi) and Illumina NovaSeq 6000 (RNA-Seq) instruments. Hi-C data were also generated from head tissue of ilLamSuff1 using the Arima2 kit and sequenced on the Illumina NovaSeq 6000 instrument. Genome assembly, curation and evaluation Assembly was carried out with Hifiasm ( Cheng et al. , 2021 ) and haplotypic duplication was identified and removed with purge_dups ( Guan et al. , 2020 ). The assembly was then scaffolded with Hi-C data ( Rao et al. , 2014 ) using YaHS ( Zhou et al. , 2023 ). The assembly was checked for contamination and corrected as described previously ( Howe et al. , 2021 ). Manual curation was performed using HiGlass ( Kerpedjiev et al. , 2018 ) and Pretext ( Harry, 2022 ). The mitochondrial genome was assembled using MitoHiFi ( Uliano-Silva et al. , 2022 ), which runs MitoFinder ( Allio et al. , 2020 ) and uses these annotations to select the final mitochondrial contig and to ensure the general quality of the sequence. A Hi-C map for the final assembly was produced using bwa-mem2 ( Vasimuddin et al. , 2019 ) in the Cooler file format ( Abdennur & Mirny, 2020 ). To assess the assembly metrics, the k -mer completeness and QV consensus quality values were calculated in Merqury.FK ( Rhie et al. , 2020 ). The genome was analysed within the BlobToolKit environment ( Challis et al. , 2020 ) and BUSCO scores ( Manni et al. , 2021 ) were calculated.

PMC Copyright notice The article reports a genome assembly of the carpet moth Lampropteryx suffumata, which is a widespread species with longitudinal range across the Eurasia and the North America. The genome sequence data will facilitate phylogenetics, biogeography and population genetic studies. As part of the Darwin Tree of Life project, this Data Note article follows a standardized format, and presents sufficient details of research materials and analysis procedures. I think the article is well prepared. My only minor suggestion is maybe the authors can provide more details such as parameter configurations of specific tools using in some key analyses, if the authors also think this is necessary.

PMC Copyright notice The project continues to produce quality resources for the insect genomics community. The methods are sound and relatively well documented. The article needs a few more details to be reasonably reproducible. Abstract. There is no justification within the abstract, just results. At least a sentence that this was part of a large survey of insects is needed. And one sentence for its possible value. Keywords. Not present. Background. There is little true motivation for this study in the introduction. Nothing wrong is said, but the reader has little idea why the work was done. Almost all the details of its life history are irrelevant to the reader. Figure 2/3/4/5 titles. These should be informative and tell the reader what you would like them to understand about the data; e.g., Fig 3. Little contamination was found in the final genome assembly. Figure 4. has very little information and can easily be summarized as a sentence in the results. The same is true of Fig 5 All parameter setting if they were different from default of each piece of bioinformatic software needs to be specified. Just put a sentence to begin that everything was default unless specified otherwise. What assessment was done to ensure that default was adequate? A reasonable, likely slightly high, number of genes is predicted. However, the reader has very little understanding of how these were evaluated beyond their initial generation. What QC beyond an automated annotation was done? One annotation run with default parameters should come with a strong disclaimer that any further work on specific gene families requires QC on the part of the user because the current annotation is a guide only. What is the BUSCO percentage of the predicted gene set? That is an absolute minimum for a reader to be able to assess the minimum quality of the annotation. How many orthogroups with other insects, etc? Table 3 is of little to no value and contains much duplicated information. Just add the version numbers of software used in line at the appropriate places in the methods section. Is the Ethics statement needed? It just says the provider of the sample should meet some agreed upon standard, but does not actually say that they did in this case. Either drop the statement or actually say the standard was met for this sample. This is not a paper about the standards of collection. Add something to the report that contextualize the research for the reader. Is this species the first of a taxon to be assembled, is it an outgroup to some established model species, is it now possible to investigate some interesting aspect of the species biology, etc? This does not to be extensive or highly directed, but there is currently no justification of this work outside of the Data Availability Statement. Even Data Note should contain rationale for the work. Are sufficient details of methods and materials provided to allow replication by others? Partly Is the rationale for creating the dataset(s) clearly described? Yes Are the datasets clearly presented in a useable and accessible format? Yes Are the protocols appropriate and is the work technically sound? Yes Reviewer Expertise: Behavior, Reproduction, Genetics, Genomics, Epigenetics, Insects I confirm that I have read this submission and believe that I have an appropriate level of expertise to confirm that it is of an acceptable scientific standard, however I have significant reservations, as outlined above.

PMC Copyright notice Thank you for reviewing this data note. Several of the comments raise broader points about the scope and purpose of data notes. While we have addressed points where clarification was appropriate, the manuscript intentionally follows the established data note format, which is designed to describe the generation, structure and quality of a dataset rather than to present biological interpretation or comparative analyses. Abstract: We have added a sentence stating that this genome assembly was generated as part of a large-scale eukaryote sequencing effort within the Darwin Tree of Life project. Keywords: These are provided in article metadata and appear in the PDF version. This is determined by the journal layout rather than the manuscript content. Background and rationale: The Background section provides a concise rationale for sequencing this species in the context of the Darwin Tree of Life programme. This programme aims to generate high-quality reference genomes across taxonomic breadth rather than to address a single hypothesis for each species. We have reviewed available sequence data and added a sentence to the background, which supports the importance of the genome presented here. Figures 2–5: These figures present standard quality assessments used across genome data notes, allowing consistency and comparability across studies. Their purpose is to summarise assembly properties and quality metrics rather than to test hypotheses. Parameter settings and defaults: All analyses were run using standard pipelines with default parameters unless otherwise stated. We have added a link to the GitHub repository for Tree of Life production code. Genome annotation and quality control: Genome annotation was produced by an external annotation team using established automated workflows. We link to these resources to ensure accessibility for users, but the annotation was not generated or curated by the authors of this manuscript. Table 3: (Now Table 4.) is retained as a consolidated reference for software tools and repositories used. Listing version numbers inline throughout the Methods would substantially reduce readability. We note that reviewer preferences on this point vary, and the current presentation aligns with other published data notes. Ethics statement: The Ethics statement is a mandatory requirement for our institute and reflects compliance with agreed standards for sample collection.
