Last Monday night I ran the trap once more, and a really breezy warm night yielded some welcome wandering species.
Quite often when it is warm, species will disperse from their strongholds in certain areas in the UK and move about with the humid air.
It certainly blurs the lines to what is actually defined as a genuine migrant moth, quite often even common species will migrate and bolster our populations, but species like Aroga velocella, Evergestis extimalis (both which featured in this catch and rare in the county) and of course the exploding Scrobipalpa ocellatella are really only our current population tracking north on southerly winds.
Obviously from August this gets trickier to define the parameters for a genuine migrant moth as we head into the peak migrantion period.
5 new species for the year was very good for the time of year, things started tailing off from now on but the common species are still doing really well.
Moth garden list for 2025 stands at 615 species
