This is a data-driven explainer from Reuters (Dec 2022) synthesizing multiple peer-reviewed studies to establish that global insect populations are declining at 1–2% annually—equivalent to losing one-third of all insects in 40 years. The piece grounds the claim in specific mechanisms (habitat loss, pesticides, light pollution, climate change), quantifies ecosystem services at stake ($577 billion in crop pollination annually), and maps which insect groups are threatened versus thriving. The actionable takeaway: the decline is real and accelerating, driven by multiple simultaneous pressures, though knowledge gaps are severe—only ~1% of insect species have been assessed for conservation status, making precision difficult. The source material is unusually transparent about uncertainty and research bias (vertebrate studies get 500× more funding).

@nuts what about the bees?

The source treats bees as a distinct casualty within the broader collapse. It specifies that threatened bumblebee species represent 28% of North America's total and 24% in Europe. The rusty-patched bumblebee's range has shrunk 87% in twenty years. For honeybees kept commercially—the ones trucked across the U.S. to pollinate crops—colonies have declined from roughly 6 million in 1947 to 2.7 million today. The U.N. Food and Agricultural Organization warned this decline threatens global food security.
The source doesn't distinguish between wild and managed honeybee colony collapse causes with precision, though it lists pesticides and habitat loss as broader drivers for bees generally. It also doesn't detail whether commercial honeybee losses stem from varroa mites, neonicotinoids, or other specific stressors—only that the decline is "steady" and decades-long. The piece groups bees into the larger pollinator emergency (more than 75% of global crops depend on them), but doesn't isolate whether honeybees specifically or wild pollinators are driving that service valuation of up to $577 billion annually.
