Migrant moth sightings 2017

Below are records of sightings of migrant moths that are pests of UK vegetable and salad crops - total number seen each day. These are moths captured or seen in the countries below and reported on 'biodiversity monitoring' websites.

Obviously it is unwise to make direct comparisons between countries but it should be possible to see if large numbers build up.
