With -3c in the garden last night I think the mothtrapping year is over now. 2016 has been my best year in terms of the number of species recorded by a fair distance and the first time I've recorded over 300 species in the year. The 318 total included 6 new macro and 16 new micro species for the garden list.  The 2 most obvious factors involved here are probably: 1. Using a 40W actinic trap instead of the 6W model I've used for the past 16 years. 2. The fine weather this summer from mid July until well into September. The table below summarises my moth numbers from 2010 and although not strictly comparable it still reveals somthing interesting. Despite a record number of species the total moths trapped still didn't reach the numbers achieved in the smaller actinic trap in 2010 and 2011.
