206 nights trapping (58 with 20w Wemlite (mostly in the winter months) and 148 with 125w MV)
538 species recorded (19381 individuals) 305 macros (14 new for the garden) and 233 micros (25 new)
Dewick's Plusia and 9 Clearwing species were to pheromone lures along with a number of the micros.
Notable new macros included Autumnal Rustic, Cypress Pug, Delicate, Dewick's Plusia, Hornet Moth, Oak Rustic and Sallow Clearwing. It was also pleasing to record 3 Silver Cloud and another Raspberry Clearwing.
The pick of the micros were Caloptilia honoratella and Cochylis flaviciliana.
In terms of numbers of the "common" macros Heart and Dart and Large Yellow Underwing were lower than previous years. On the other hand Lesser Broad-bordered Yellow Underwing with 689 individuals was the third most common species. Small Square-spot with 170 continued to improve from its low of 4 in 2019.
Nothing special in terms of migrants but 152 Rush Veneer Nomophilia noctuella was remarkable. I also recorded 8 Ostrinia nubialis mostly in September and I wonder if they are breeding in the fields of Maize which is being grown in increasing amounts locally for the nearby biodigester.
Hi Andy,
ReplyDeleteOstrinia nubilalis would seem to have taken up residence locally to me as well. I had a singleton in the garden back in 2006 then no more until further singletons in 2018 and 2019. Since then the annual totals have increased significantly, both males and females: 2020 (8), 2021 (20) & 2022 (48). I'm also seeing it more and more regularly when trapping at other sites in Bucks and my final tally for 2022 within the county was 54 (30 males, 24 females).
Hi Andy and Dave,
ReplyDeleteI my much more modest catches to light (approx weekly in my garden) over the last few years in south Oxon (VC22), I did not see Ostrinia nubilalis until 2019 (one in July), then 2 in both 2020 and in 2021, and lastly 5 in 2022. While most were caught in July, in 2022 the last two were in Aug and Sept (this spread seems to be general, as shown e.g., by the phenology chart at the Hants Moths website).
