The claim that “Climate Change is Killing all the Amazon Dung Beetles” is false and a gross exaggeration.

Recent peer-reviewed research (as of March–April 2026) shows that rising temperatures linked to climate change are stressing dung beetle populations in parts of the Amazon, contributing to reduced diversity and abundance in vulnerable lowland areas.

However, there is zero evidence of total extinction, widespread “killing off” of every beetle, or even uniform collapse across the entire Amazon basin. Populations persist, and the insects remain ecologically active in many areas.

A study published in Proceedings of the Royal Society B (led by researchers from the Universities of Würzburg and Bremen) analyzed dung beetle communities along a full elevation gradient in Peru’s Kosñipata Valley (Amazon lowlands at ~250 m to Andean highlands at ~3,500 m).

Data were collected in 2022–2023 using baited traps, camera traps for mammal activity (as a proxy for dung/food availability), and thermal measurements.

Temperature is the dominant factor—far more important than food supply or soil moisture. Diversity and abundance peaked at ~500 m elevation (optimal temperatures) and dropped sharply in the hotter lowlands below that.

Lowland beetles are already operating near or beyond their upper thermal limits (small or negative “thermal safety margins”), making them vulnerable to further warming.

The authors conclude that additional climate-driven warming in the Amazon lowlands could reduce species richness and population sizes, potentially disrupting nutrient cycling, seed dispersal, and forest health—even in intact, undisturbed rainforests. Up to half of Amazon lowland insects may face similar heat thresholds.

Press coverage (USA Today, Phys.org, university releases) accurately reflects this: “Climate change may be worsening life for dung beetles” or “Climate change threatens dung beetles in the Amazon.” No reputable source claims they are being “killed all.”

Not “all” beetles: The studies show declines in diversity, abundance, or range for many (especially lowland or forest-specialist) species, but not uniform wipeout. Some beetles show behavioral adaptations, like digging deeper nests to escape heat. Tropical species may be less flexible than temperate ones, but local refugia (higher elevations, intact forests) and protected areas still support diverse communities (e.g., surveys in Brazilian reserves found dozens of species).

Not solely climate change: Deforestation, agriculture, fires, and fragmentation are major drivers. El Niño events (natural variability intensified by warming) played a key role in observed collapses. Climate acts as a threat multiplier rather than the sole killer.

“Killing” vs. projected risk: Much evidence involves observed drops after extremes or modeling of future risks. Populations persist, though stressed. No study claims current or imminent extinction of all Amazon dung beetles.

Ecosystem implications: Declines matter because beetles aid forest regeneration. However, claims of total loss overstate the data and ignore resilience factors.

Media and modeling studies project range contractions or functional losses for some species under high-warming pathways, but these are not “killing all.”

In summary, climate change poses a legitimate, growing risk to Amazon dung beetles (especially via heat stress in lowlands), with real ecological consequences if unchecked. But the absolute claim of it “killing all” them is hyperbolic misinformation.

The beetles are stressed in places—not eradicated. Ongoing monitoring, forest protection, and emission reductions would help safeguard them and the services they provide.
