Migrant moth sightings 2019

Tuesday 30th July - update - you may be interested in this short video on Twitter. Hundreds of diamond-back moths in Fife!

As in 2017 and 2018 we are summarising records of sightings of migrant moths (diamond-back moth and silver Y moth) that are pests of UK vegetable and salad crops. 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.
