The glow‐worm Lampyris noctiluca (Linnaeus, 1767) (Coleoptera: Lampyridae) is thought to be declining in the United Kingdom. Yet, much of the evidence for this is anecdotal, with a shortage of standardised long‐term data to investigate temporal changes in abundance. We present an 18‐year time series of standardised transect surveys for glowing adult females at 19 sites within south‐east England (Essex) from 2001 to 2018. We used generalised additive mixed models (GAMMs) to control for varying… 
Further evidence for a global decline of the entomofauna
Evidence is added that changes in species richness and diversity indices are inconsistent and do not reflect intraspecific population changes over time, although a lack of long‐term monitoring records prevents a proper assessment for tropical regions.
Interpreting insect declines: seven challenges and a way forward
Many insect species are under threat from the anthropogenic drivers of global change. There have been numerous well‐documented examples of insect population declines and extinctions in the scientific
The duration of artificial light defines sexual signalling in the common glow-worm
Artificial light at night is increasing globally, interfering with both sensory ecology and temporal rhythms of organisms, from zooplankton to mammals. This interference can change the behaviour
Spotlight on insects: trends, threats and conservation challenges
There is mounting concern over the conservation status and long‐term trends in insect populations. Many insect populations have been reported to be falling and many species are threatened with
Reproduction under light pollution: maladaptive response to spatial variation in artificial light in a glow-worm
The results indicate that glow-worms are unable to respond to spatial variation in artificial light, which may be a factor in their global decline and supports the hypothesis that animals often lack adaptive behavioural responses to anthropogenic environmental changes.
Evaluating firefly extinction risk: Initial red list assessments for North America
At least 18 species from the United States and Canada are threatened with extinction due to various pressures, including habitat loss, light pollution, and climate change (sea level rise and drought), and the need for further study is highlighted.
Beyond the Decline of Wild Bees: Optimizing Conservation Measures and Bringing Together the Actors
This review presents a general and up-to-date assessment of the conservation methods, as well as their efficiency and the current projects that try to fill the gaps and optimize the conservation measures for wild bees.
Nocturnal pollination: an overlooked ecosystem service vulnerable to environmental change
There is evidence that nocturnal species are providers of pollination services (including pollination of economically valuable and culturally important crops, as well as wild plants of conservation concern), but how little is known about the scale of such services is highlighted.
Artificial lighting impairs mate attraction in a nocturnal capital breeder
Artificial lighting at night (ALAN) impedes female glow worms’ ability to attract males with their glow, implicating ALAN in glow worm fecundity and long-term population survival.
Time Series Analysis of Land Cover Change in Dry Mountains: Insights from the Tajik Pamirs
It is found that greening and browning trends coexist and that they vary according to the land cover class, topography, and geographical distribution.


Response of glow-worms Lampyris noctiluca to scrub clearance on a sea wall flood defence at Creeksea, Essex, England
SUMMARY: The response of glow-worms Lampyris noctiluca to winter scrub clearance on a sea wall flood defence in Essex, England was monitored. The number of glowing adult females did not show a
Declining abundance of beetles, moths and caddisflies in the Netherlands
The results broadly echo recent reported trends in insect biomass in Germany and elsewhere, suggesting that heavy species did not contribute disproportionately to biomass decline.
Predicting a global insect apocalypse
The last 3 years have seen a global outbreak of media headlines predicting a global insect apocalypse and a subsequent collapse of natural ecosystems, a so‐called ‘ecological armageddon’ resulting in
Moth biomass increases and decreases over 50 years in Britain
Analysing data from the world’s longest-running insect population database, the authors find that recent declines in UK moth biomass were preceded by a larger increase, highlighting the need for long-term data to detect trends and identify their causes robustly.
Mitigating the precipitous decline of terrestrial European insects: Requirements for a new strategy
Severe decline in terrestrial insect species richness, abundance, flying biomass, and local extinctions across Europe are cause for alarm. Here, we summarize this decline, and identify species
Are neonicotinoid insecticides driving declines of widespread butterflies?
Build models of the UK population indices from 1985 to 2012 for 17 widespread butterfly species that commonly occur at farmland sites to show whether there is a causal link between neonicotinoid usage and the decline of widespread butterflies or whether it simply represents a proxy for other environmental factors associated with intensive agriculture.
Arthropod decline in grasslands and forests is associated with landscape-level drivers
The results suggest that major drivers of arthropod decline act at larger spatial scales, and are associated with agriculture at the landscape level, which implies that policies need to address the landscape scale to mitigate the negative effects of land-use practices.
More than 75 percent decline over 27 years in total flying insect biomass in protected areas
This analysis estimates a seasonal decline of 76%, and mid-summer decline of 82% in flying insect biomass over the 27 years of study, and shows that this decline is apparent regardless of habitat type, while changes in weather, land use, and habitat characteristics cannot explain this overall decline.

Findings are consistent with recent dramatic declines in insect abundance in Europe and North America with consequences for the rate of food provisioning of barn swallow offspring, the abundance of aerially insectivorous birds and bottom‐up trophic cascades.
Low levels of light pollution may block the ability of male glow-worms (Lampyris noctiluca L.) to locate females
Light pollution has been proposed as a factor in the decline of Lampyris noctiluca because it has the potential to interfere with reproductive signaling and has been shown to impact the ability of
