Insects around Amsterdam

Amsterdam, North Holland, The Netherlands

Every measure here is worked out per 5 degree square, so this covers the wider area around Amsterdam (50° to 55° latitude, 0° to 5° longitude, about 550 km across), not the city alone. Counts are shares of all insects records in the same weeks, so busier stations do not inflate them (methods).

Expected in the next six weeks
