Genome assembly of a nocturnal butterfly (Macrosoma leucophasiata) reveals convergent adaptation of visual genes.

Nearly all animals exhibit a preferred period of daily activity (diel-niche), strongly influenced by the light environment. Vision is a sensory system that is strongly adapted to light, and evolutionary transitions to novel light environments can impose strong constraints on eye evolution, color, and motion vision. While the genetic and neural basis of visual adaptation are well-studied in a few model systems, our understanding across the tree of life remains incomplete.

A near chromosome-level genome assembly of a ghost moth (Lepidoptera, Hepialidae).

Ghost moths are an unusual family of primitive moths (Lepidoptera: Hepialidae) known for their large body size and crepuscular adult activity. These moths represent an ancient lineage, frequently have soil dwelling larvae, and are adapted to high elevations, deserts, and other extreme environments. Despite being rather speciose with more than 700 species, there is a dearth of genomic resources for the family.

The genome sequence of the 6-spot burnet, (Linnaeus, 1758).

We present a genome assembly from an individual female (6-spot burnet; Arthropoda; Insecta; Lepidoptera; Zygaenidae). The genome sequence is 365.9 megabases in span.

Phylogenomics recovers multiple origins of portable case making in caddisflies (Insecta: Trichoptera), nature's underwater architects.

Caddisflies (Trichoptera) are among the most diverse groups of freshwater animals with more than 16 000 described species. They play a fundamental role in freshwater ecology and environmental engineering in streams, rivers and lakes. Because of this, they are frequently used as indicator organisms in biomonitoring programmes.

Genomic resources of aquatic Lepidoptera, Elophila obliteralis and Hyposmocoma kahamanoa, reveal similarities with Trichoptera in amino acid composition of major silk genes.

While most species of butterflies and moths (Lepidoptera) have entirely terrestrial life histories, ∼0.5% of the described species are known to have an aquatic larval stage. Larvae of aquatic Lepidoptera are similar to caddisflies (Trichoptera) in that they use silk to anchor themselves to underwater substrates or to build protective cases.

Evolutionary genomics of three agricultural pest moths reveals rapid evolution of host adaptation and immune-related genes.

Background: Understanding the genotype of pest species provides an important baseline for designing integrated pest management (IPM) strategies. Recently developed long-read sequence technologies make it possible to compare genomic features of nonmodel pest species to disclose the evolutionary path underlying the pest species profiles. Here we sequenced and assembled genomes for 3 agricultural pest gelechiid moths: Phthorimaea absoluta (tomato leafminer), Keiferia lycopersicella (tomato pinworm), and Scrobipalpa atriplicella (goosefoot groundling moth).

CRISPR-based diagnostics detects invasive insect pests.

Rapid identification of organisms is essential for many biological and medical disciplines, from understanding basic ecosystem processes, disease diagnosis, to the detection of invasive pests. CRISPR-based diagnostics offers a novel and rapid alternative to other identification methods and can revolutionize our ability to detect organisms with high accuracy. Here we describe a CRISPR-based diagnostic developed with the universal cytochrome-oxidase 1 gene (CO1).

The genome sequence of the peacock moth, (Linnaeus, 1758).

We present a genome assembly from an individual male (the peacock moth; Arthropoda; Insecta; Lepidoptera; Geometridae). The genome sequence is 394 megabases in span. The majority of the assembly (99.

CRISPR-based diagnostics detects invasive insect pests.

Rapid identification of organisms is essential across many biological and medical disciplines, from understanding basic ecosystem processes and how organisms respond to environmental change, to disease diagnosis and detection of invasive pests. CRISPR-based diagnostics offers a novel and rapid alternative to other identification methods and can revolutionize our ability to detect organisms with high accuracy. Here we describe a CRISPR-based diagnostic developed with the universal cytochrome-oxidase 1 gene (CO1).

A global phylogeny of butterflies reveals their evolutionary history, ancestral hosts and biogeographic origins.

Butterflies are a diverse and charismatic insect group that are thought to have evolved with plants and dispersed throughout the world in response to key geological events. However, these hypotheses have not been extensively tested because a comprehensive phylogenetic framework and datasets for butterfly larval hosts and global distributions are lacking. We sequenced 391 genes from nearly 2,300 butterfly species, sampled from 90 countries and 28 specimen collections, to reconstruct a new phylogenomic tree of butterflies representing 92% of all genera.

Mezcal worm in a bottle: DNA evidence suggests a single moth species.

Mezcals are distilled Mexican alcoholic beverages consumed by many people across the globe. One of the most popular mezcals is tequila, but there are other forms of mezcal whose production has been part of Mexican culture since the 17th century. It was not until the 1940-50s when the mezcal worm, also known as the "tequila worm", was placed inside bottles of non-tequila mezcal before distribution.

The genome sequence of the sallow kitten, (Clerck, 1759).

We present a genome assembly from an individual male (the sallow kitten; Arthropoda; Insecta; Lepidoptera; Notodontidae). The genome sequence is 736 megabases in span. The entire assembly (100%) is scaffolded into 29 chromosomal pseudomolecules, with the Z sex chromosome assembled.

Long-read HiFi sequencing correctly assembles repetitive silk genes in new moth and caddisfly genomes.

Insect silk is a versatile biomaterial. Lepidoptera and Trichoptera display some of the most diverse uses of silk, with varying strength, adhesive qualities, and elastic properties. Silk fibroin genes are long (>20 Kbp), with many repetitive motifs that make them challenging to sequence.

Anti-bat ultrasound production in moths is globally and phylogenetically widespread.

Warning signals are well known in the visual system, but rare in other modalities. Some moths produce ultrasonic sounds to warn bats of noxious taste or to mimic unpalatable models. Here, we report results from a long-term study across the globe, assaying moth response to playback of bat echolocation.

First Annotated Genome of a Mandibulate Moth, Neomicropteryx cornuta, Generated Using PacBio HiFi Sequencing.

We provide a new, annotated genome assembly of Neomicropteryx cornuta, a species of the so-called mandibulate archaic moths (Lepidoptera: Micropterigidae). These moths belong to a lineage that is thought to have split from all other Lepidoptera more than 300 Ma and are consequently vital to understanding the early evolution of superorder Amphiesmenoptera, which contains the order Lepidoptera (butterflies and moths) and its sister order Trichoptera (caddisflies). Using PacBio HiFi sequencing reads, we assembled a highly contiguous genome with a contig N50 of nearly 17 Mb.

Review of recent taxonomic changes to the emerald moths (Lepidoptera: Geometridae: Geometrinae).

Background: The subfamily Geometrinae (Lepidoptera: Geometridae), commonly known as emerald moths, is an ecologically diverse group of moths with over 2,500 described species. Many taxonomic and phylogenetic studies of Geometrinae have been undertaken in the past decade, resulting in hundreds of new taxonomic changes since online publication of the most recent checklist in December 2007.

New Information: This review synthesises the last 12 years of alpha-taxonomic research in Geometrinae.

Practical rare event sampling for extreme mesoscale weather.

Extreme mesoscale weather, including tropical cyclones, squall lines, and floods, can be enormously damaging and yet challenging to simulate; hence, there is a pressing need for more efficient simulation strategies. Here, we present a new rare event sampling algorithm called quantile diffusion Monte Carlo (quantile DMC). Quantile DMC is a simple-to-use algorithm that can sample extreme tail behavior for a wide class of processes.

Phylogenetics of moth-like butterflies (Papilionoidea: Hedylidae) based on a new 13-locus target capture probe set.

The Neotropical moth-like butterflies (Hedylidae) are perhaps the most unusual butterfly family. In addition to being species-poor, this family is predominantly nocturnal and has anti-bat ultrasound hearing organs. Evolutionary relationships among the 36 described species are largely unexplored.

Preserving and vouchering butterflies and moths for large-scale museum-based molecular research.

Butterflies and moths (Lepidoptera) comprise significant portions of the world's natural history collections, but a standardized tissue preservation protocol for molecular research is largely lacking. Lepidoptera have traditionally been spread on mounting boards to display wing patterns and colors, which are often important for species identification. Many molecular phylogenetic studies have used legs from pinned specimens as the primary source for DNA in order to preserve a morphological voucher, but the amount of available tissue is often limited.

Blood, sweat, and tears: a review of the hematophagous, sudophagous, and lachryphagous Lepidoptera.

Although adult Lepidoptera are not often considered medically relevant, some butterflies and moths are notorious for their consumption of mammalian body fluids. These Lepidoptera can be blood-feeding (hematophagous), tear-feeding (lachryphagous), or sweat-feeding (we use the term "sudophagous"). Blood-feeding Lepidoptera have been observed piercing the skin of their hosts during feeding, while tear-feeding Lepidoptera have been observed frequenting the eyes of hosts in order to directly obtain lachrymal fluid.

Heel neuroma: a case study.

Unlabelled: This article reviews the diagnosis, pathology, and treatment of plantar heel neuroma, an entity that has previously been described and recognized, yet one that we feel warrants further review because of the prevalence of plantar heel pain that does not respond to the usual array of treatments. We feel that neuroma of the medial calcaneal nerve often goes undiagnosed, and may progress to a severely painful condition that requires surgical intervention. In this article, we describe another case of heel neuroma in an otherwise healthy patient with a history of chronic plantar heel pain that was unresponsive to a wide array of nonsurgical treatments.
