Long-term monitoring

Lacanobia grandis has been included in long-term studies of Lepidoptera. Research from a 29-year light trap study in Prague (1967–1995) used related Lacanobia (L. aliena) to demonstrate that detecting reliable long-term trends in abundance requires at least 15 years of continuous data collection, with 20–25 years preferred for robust conclusions.
