Moth trapping: 23 Species in our 3 traps last night, a slight reduction on recent captures owing to the windy night. Today's focus moth is the Beet moth: It is a growing 'pest' on agriculture with larvae defoliating Beet crops making them susceptible to rot and reducing crop yields up to 25%, new pesticides have been developed however remain expensive. - BBC. The moth had only become a problem in past 5 years for farmers, matching the time period they have been occurring on our site which supports the hypothesis they entered the country through Suffolk.  

   Beet moth (Scrobipalpa ocellatella), 6 years ago we had our first one, now they regularly show up in our traps.
