A new analysis pulls together ten years of nightly moth trap records from [number] sites and finds the headline everyone expected, plus one nobody did.
The expected part: total moth abundance is down, and the decline is steepest in the species that specialise on a single plant. The unexpected part: generalist species in urban gardens are holding steady, and a few are increasing.
Reading it carefully
This is not good news dressed up. A garden full of common moths is not a functioning ecosystem; it is a lifeboat. But it does tell you where intervention is cheapest — the specialists need their host plants, and host plants need somewhere to grow.
The paper is careful about its own limits: trap records depend on weather, on who was running the trap, and on the trap itself. The authors spend four pages on this. Read those four pages before quoting the number.
