Subjects: Biology, Entomology, Life Sciences, Population Biology, Public Health, Statistical Methodology, Virus Diseases
The invasive Asian tiger mosquito (Aedes albopictus) has become an important public health concern in Italy, particularly in the Po Valley area, where its biting behaviour and nuisance have contributed to multiple outbreaks of mosquito-borne diseases over the last two decades. To address this growing threat, the Emilia-Romagna region has conducted intensive mosquito monitoring efforts since 2010, [...]
Native bee genus diversity within bee-friendly urban gardens varies little along an urbanization gradient
Published: 2025-09-30
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology
Urban bee populations are threatened by ongoing habitat loss and fragmentation. Bee-friendly gardens with abundant forage and nesting resources may help offset these pressures, but attributes of the broader urban landscape could also play an important role. We explored bee diversity within 32 bee-friendly gardens distributed throughout the city of Kelowna, British Columbia. Our objectives were to [...]
What defines an urban butterfly? Life history traits and habitat associations of butterflies in urban environments
Published: 2025-09-19
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Forest Sciences, Life Sciences
Urban areas are encroaching onto semi-natural areas the world over, driving species assemblages into homogenisation. A better understanding of the life history and habitat association traits can help support management efforts to improve urban biodiversity. Urban areas present an ecological filter, limiting the number of species present compared to the wider countryside. What characteristics help [...]
Dietary preferences and behaviour of the Southern Lesser Bushbaby Galago moholi (Loriformes: Galagidae) foraging at an entomological light trap
Published: 2025-09-14
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences
The Southern Lesser Bushbaby Galago moholi is a small, nocturnal, strepsirrhine primate, native to Sub-Saharan Africa. Previously considered a strict dietary specialist on tree exudates and insects, recent observations have revealed hitherto unappreciated plasticity in its feeding behaviour, encompassing fruits and even small vertebrates. While arthropods are an important seasonal component of [...]
Catalogue of Papilionoidea from Noguera de Albarracín (Teruel, Spain), including new distributional data for the Sierra de Albarracín (Insecta: Lepidoptera)

Subjects: Animal Sciences, Biology, Entomology, Life Sciences, Zoology
We present a catalogue of butterflies from Noguera de Albarracín (Teruel, Spain), based on field surveys conducted in 2024 and 2025 within the framework of the Iberozoa Entomology Course. A total of 52 species were recorded, representing 20.15% of the Iberian butterfly fauna. The material belongs to 5 families, 13 subfamilies, 33 genera and 52 species. Lycaenidae was the richest family with 16 [...]
Tracking the hidden niches: Movement-based insights into northern lapwing intraspecific variation and conservation
Published: 2025-08-01
Subjects: Animal Sciences, Behavior and Ethology, Biodiversity, Entomology, Life Sciences, Ornithology, Other Animal Sciences, Other Ecology and Evolutionary Biology, Population Biology, Zoology
Context. Global monitoring data reveal farmland bird population declines, primarily driven by agricultural intensification, chemical inputs, and climate shifts. The northern lapwing (Vanellus vanellus), a ground-nesting wader adapted to lowland agricultural matrices, exemplifies this decline across Europe. Objectives. This study quantified intraspecific variation in habitat selection to evaluate [...]
Illegal cattle trade brings New World Screwworm to wildlife and continues to destroy protected areas in Mesoamerica
Published: 2025-07-30
Subjects: Agriculture, Animal Diseases, Animal Sciences, Biodiversity, Entomology, Life Sciences, Other Ecology and Evolutionary Biology, Parasitic Diseases, Parasitology, Public Health, Veterinary Preventive Medicine, Epidemiology, and Public Health
The New World Screwworm (Cochliomyia hominivorax; “screwworm”) is a parasitic fly historically endemic to the Americas. Females lay eggs in open wounds of warm-blooded animals, including humans. The emerging larvae feed on the host’s living tissue, often resulting in severe damage and potentially death. After five decades of coordinated efforts, the screwworm was successfully eradicated from [...]
A comprehensive dataset on pollinator diversity, visitation rates, individual-based traits, and pollination success across four plant species in an urban garden experiment

Subjects: Artificial Intelligence and Robotics, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences
1. Natural history museums often curate large collections of pinned insects. These collections represent invaluable records of biodiversity information, ecological patterns and phenotypic variation. A common goal of museums is to create digital versions of these records for curation and research purposes. However, traditional methods of specimen imaging and metadata transcription are [...]
Emerging tools to advance neuroethology in butterflies and moths
Published: 2025-06-30
Subjects: Behavior and Ethology, Entomology, Other Ecology and Evolutionary Biology
Butterflies and moths have played historically important roles in developing our understanding of both ecology and evolutionary biology, and neuroethology. In both contexts, the diversity of behavioral strategies and specializations displayed by different Lepidoptera make them informative case studies. However, as in neuroscience more broadly, lepidopteran neuroethology has tended to focus on [...]
Two Metschnikowia nectar yeast species have similar volatile profiles, but elicit differential foraging in bee pollinators
Published: 2025-06-18
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Microbiology, Organismal Biological Physiology, Other Microbiology
1. Nectar yeasts are a highly specialized group of fungi that may play key roles in pollination ecology. Nectar yeasts lack an independent dispersal mechanism to access new habitats with fresh resources. Yeasts, bumble bee pollinators, and flowering plants likely take part in a series of diffuse mutualisms, wherein yeast attract bees that provide phoretic travel between flowers. This [...]
Elevating the importance of Risk of Bias assessment for ecology and evolution
Published: 2025-06-16
Subjects: Agriculture, Animal Sciences, Biodiversity, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Marine Biology, Microbiology, Plant Sciences, Research Methods in Life Sciences
Systematic reviews and meta-analyses are key evidence synthesis methods informing research and policy. An assessment of the Risk of Bias (RoB) in included studies is normally considered an essential component of these. However, RoB assessment is rare in ecology and evolutionary biology (EEB), and tools from other fields are seldom adopted. To identify reasons for this limited uptake, we surveyed [...]

Filling Monitoring Gaps for Data-deficient Species Using Annual Occupancy Predictions from Co-occurrence Models
Published: 2025-05-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences
Fragmented surveys and limited monitoring exclude most invertebrate species from conservation policy. We present a framework that generates annual occupancy predictions using species distribution models (SDMs) to reconstruct missing trends—not to extrapolate trends, but to fill them in (the fill-in approach). Instead of filtering poor-data regions and years or relying on static environmental [...]
