Azores Moths 2023

Despite trapping nearly every night while on Corvo there wasn't much to show for it. I could only transport the LED trap which generally works better in areas of high moth density. I've been bringing a trap to Corvo for several years now but still no sign of any American migrants. I suspect we would need MVs and generators as it appears that it will be quite a challenge. Despite there being multiple American Painted Ladies and Green Darners in the UK this autumn,  nothing in the way of Nearctic entomology has been reported from the Azores despite the record breaking american bird migrant autumn.  I didn't even catch one of the American species that have colonised the Azores- White Speck (American Wainscot) or Wedgling which were numerous in previous years that I tried the trap out.

I did see a Painted Lady sp when David and I were looking for the Wood Thrush but didn't see it well enough to conclude whether an American or European. 

Anyway, here's a few of the moths that either turned up in the trap or were flying during the day.

Previous moth trapping on Azores HERE

Chevron Snout 
Maize Moth, Spoladea recurvalis 
Bloxworth Snout 
Rusty-dot Pearl I presume- there were lots of these but there is the Azores endemic Udea Azorensis out on the Azores too which if I understand correctly can only be identified on the pattern on the hind-wing 
Slender Burnished Brass- always nice to see and seemingly quite common on Corvo 
Mediterranean Brocade 
Hawkmoth sp found by David in the toilet block- presumably a Convolvulus which can be common on Corvo 
Small Angle Shades ? See comments. 
Setaceous Hebrew Character 
Bactra sp? If so the two species present on the Azores is lancealana and venosana. See comments. 
Lapastrier’s Piercer , Selania leplastriana 
Grass Webworm Herpetogramma licarsisalis 
Turnip Moth- the most numerous moth in the trap- up to five

Hi Peter, Definitely not Small Angle shades. Looks like a Common Rustic agg but cant be sure. The Bactra looks more like a Crambid...

Hi Stewart, agree that it's not a good fit for Small Angle Shades. The only Mesapamea on the Azores is the endemic one so I guess it could be that by comparing with the photos on Lepiforum, it is listed for Corvo too.
