It was a good six nights though - a decent selection of interesting moths that I don't see at home, whether they were migrants or not. We stayed six nights, 1st to 6th October, and I ran a Robinson trap every night plus an old Skinner trap whenever there was no real threat of rain (it has no protective cover), which was most nights.
Now, at home I trap every night, release the moths at first light and it seems that hardly any get retrapped the following night. Here it seemed to be different, and although I let them go at first light some of the moths were hanging around and getting re-caught on subsequent nights. So the total summed counts for the week below include moths counted on consecutive nights and are higher than the true number of individuals trapped.
Anyway, here are some of the highlights, roughly in order of interest (to me):
- Olive-tree Pearl Palpita vitrealis - 1 on 3rd, a migrant and a new moth for me (I don't count one that Dave N brought round to show me once). Presumably a pregnant female as I found some eggs where it had been sitting, and I'm pretty sure they weren't there before.

- Clancy's Rustic - 1 on 3rd, clearly a migrant (and a pretty tatty worn specimen). I saw one in a pot on Scillies once but this was the first time I've ever caught one myself. It turned out to be a good year for this species with Norfolk getting its first ever record later in the month - in fact its first 4 records!

- Four-spotted Footman - one on 4th. A migrant, a stunner, and only the second I've ever seen.

- Vestal - 1 on 3rd and 2 on 5th, presumably all migrants. I've seen these in Cornwall before, and once at home, but such amazing moths they will always be high up on any list of highlights.

Vestals, Tresidder, 5th October
- White-speck - different singles on 3rd, 4th and 5th. Also migrants I presume and a species I'd only seen twice before.

- Delicate - recorded every night with a total of 106 and a maximum of 33 on 5th. Although a migrant species I think these must now be breeding locally. The numbers would have been exceptional if they'd all been migrants, especially during a period when there wasn't an especially strong immigration evidenced by other species. Anyway, I'd only seen one before so it was great to see so many every night.
Delicates, Tresidder, 1st October
- L-album Wainscot - recorded every night with a total of 19 and a maximum of 6 on 2nd. Although a migrant species I think these are now breeding locally too. I'd only ever seen two before.
L-album Wainscots, Tresidder, 1st October
- Scarce Bordered Straw - 1 on 4th. A migrant species I've only seen on 3 occasions before.

- Brindled Ochre - singles on 2nd and 6th. I've done better for these on past trips when I've stayed at Porthgwarra, but they're always great to see and I've never seen one anywhere else.
Brinlded Ochre, Tresidder, 2nd October
- Flounced Chestnut - 1 on 3rd - only the second I've ever seen though I don't know if they're any commoner down here than they are at home?
Flounced Chestnut, Tresidder, 3rd October
- Feathered Ranunculus - recorded every night with a total of 24 and a maximum of 10 on 6th. Although this species does occur in Norfolk, mainly along the north coast and in the Norwich area, it's so far eluded me here. I've seen quite a few in Cornwall on previous trips though, but it's a fabulous moth so always a highlight.
Feathered Ranunculus, Tresidder, 1st October
- Large Ranunculus - 1 on 6th, the only new moth of the trip on the final night - a nice moth and only my fourth although some people in Norfolk get them regularly.

- Autumnal Rustic - 1 on 2nd then 9 on 5th and 3 on 6th. Another species that does occur in Norfolk but much less commonly than in the south west. I'm yet to see one in Norfolk but have seen quite a few in Cornwall before.
Autumnal Rustic, Tresidder, 2nd October
- Plum Fruit Moth Grapholita funebrana - 1 on 4th. Although I've seen a few of these at home (all but one in 2016) I don't think it's a particularly common species and not one I was expecting to see here. It was a very worn individual though.
- Little Slender Calybites phasianipennella - 1 on 2nd. A species I don't see very often - only 5 before.

- Angle Shades - recorded every night except the first with a total of 42 and a maximum of 15 on 4th. Although a common resident breeder in the UK this species is also a migrant and with these peaking at the same time as other migrants I suspect a lot of these were migrants. Although common at home I usually only get the occasional single at home so these numbers are good for me.
Angle Shades, Tresidder, 2nd October
- Rusty-dot Pearl Udea ferrugalis - recorded every night with a total of 66 and a maximum of 29 on 4th. A common migrant species that sometimes reaches home, but it also breeds locally in SW Cornwall and I'm not sure how many of these were migrants vs. locals.
- Dark Spectacle - singles on 2nd and 3rd.
Dark Spectacle, Tresidder, 2nd October
- Pinion-streaked Snout - recorded every night except the last with a total of 28 and a maximum of 14. A species I encounter fairly often at home, but never in anything like such numbers.

As you would expect, there was a variety of other insects in the moth traps too, and I'll write about these in a separate post...
