Status of Insects is an NSF-funded Research Coordination Network (RCN) focused on developing the empirical and quantitative tools needed to answer one of the largest research challenges in biodiversity science: the insect decline phenomenon.

2025年3月6日 · Of all insect groups, butterflies are the most extensively monitored. In the United States (US), butterflies have been the focus of volunteer-based and expert science monitoring programs since 1975, with dozens of local-to-regional programs now monitoring butterfly populations ().Efforts to analyze these monitoring data have focused on estimating trends within limited geographic regions ...

EntoGEM is a community-driven project that aims to compile evidence about global insect population and biodiversity status and trends. Our goal is to assess the current state of evidence in the scientific literature regarding insect declines, increases, or lack of changes over time.

Insect decline is a worldwide issue caused by habitat loss, pesticide use, pollution, invading species, intensive agriculture, and climate change. It affects flying, ground, and aquatic lineages, with Lepidoptera, Hymenoptera, Coleoptera, Odonata, Plecoptera, Trichoptera, and Ephemeroptera being especially vulnerable.

2025年3月24日 · Fewer than 1% of all insects and <8% of butterflies have so far been assessed for their global threat status, despite a growing recognition of their worldwide population declines 18,65. Our study ...

2025年3月6日 · He praised the study’s rigor and noted that the declines in butterflies, amounting to 1.3 percent per year, were in line with other recent efforts to analyze global trends in terrestrial insect ...

An ad hoc study committee of the National Academies of Sciences, Engineering, and Medicine will conduct a consensus study on the status of insects in North America to assess trends in insect abundance, identify research priorities, and suggest actions to slow insect losses in areas identified as most vulnerable and most critical to ecosystem ...

Status of Insects RCN Webinar Series. February 9, 2023. An overview of what we do and don't know about data that can be used to quantify insect trends and disentangle drivers and the ongoing EntoGEM systematic map project.

2022年6月25日 · The International Union for Conservation of Nature has assessed a total of 77,435 species of insects between 1996 and 2020, of which 18,180 (23.47%) species are reported to be threatened and the...

2022年11月8日 · Progresses: Declines of insect abundance and diversity are being reported worldwide. Anthropogenic disturbance, climate change, and other factors contribute to this crisis. Strategies & Prospects: Studies of insect biodiversity have expanded from early comparisons of species richness on composition to multiple dimensions of diversity. Current ...
