The year is more or less finished so a summary of 2025, there was a lot of moth trapping in the field. So… I made 3,466 records 778 different species, 480 of those were moths. 129 species were new to me during 2025. Moths accounted for 74 new species for me so I now have 602 moths on my life list.

Phalonidia affinitana - New to Channel Islands

A few moths last night, cold and breezy this morning, but nice to see Autumnal Rustic, my fist since 2020 and only third ever, not a common moth in my garden. Photo's: Autumnal Rustic Turnip Moth Rusty Dot Pearl Feathered Ranunculus

Long-tailed Skua. Great bird but not very helpful for photo's staying clear of the boat.

The Fulmar were very obliging today, really like this shot.

Low numbers in the trap last night but a Rosy Underwing made up for that. #Guernsey #mothsmatter

Two options for this Caloptilia, both nice to get. Questions is, which one is it? @mothiduk.bsky.social @gyrcrakes.bsky.social

Trapped in a wooded valley on the South Coast of Guernsey last night. A small site. 69 species including a few very nice ones. Photo's of some of the new to me moths below. See Alt text for names.

Some moths from a La Societe Entomology Section outing to Grand Pre NR on 12th July. We ran 6 traps and captured 97 species of moth. The bug is one of the Saldidae - Shore Bugs - Chartoscirta cincta and these are a new species for Guernsey. Photo's labelled in Alt Text.

This might be interesting. Agdistis sp Plume Moth on the cliffs last night in Guernsey. Will have to investigate the differences @mothiduk.bsky.social

@mothiduk.bsky.social looks like this might be Metalampha sp and more like M.cinnamomea with the dark colour. VC113 Guernsey. Heavy migrant night. Any comments or opinions please?

Andy Marquis @andym105.bsky.social · 19/06/2025

A few nice oce moths this morning. Not a huge number of migrants but a pair of Feline is pretty special and I assume migrant as I've never had one in 12 years of trapping here. Also Marbled White Spot rare for here, a few Small Mottled Willow, Dark Swordgrass as common migrants.

Andy Marquis @andym105.bsky.social · 17/05/2025

It's very wet out, but hopefully these heavy showers will subside and the gentle F2/3 originating in North Africa and coming across the continent will bring us something nice as well as whatever local moths are about ready for tomorrow's #bioblitz. #mothsmatter

A few things from the big low tide today. Common Spider Crab - Macropedia rostrata Common Squat Lobster Aeolidia papillosa Geitodoris planata maybe or another suggestion of Atagema gibba, waiting for experts

First moth trap of 2025, I am a little behind... Moths: 1. Dotted Border 2. Seraphim 3. Acleris literana (new one for me) 4. Caloptilia stigmatella Also had Waved Umber, Hebrew Character, Common Quaker, Rusty Dot Pearl and Bloxworth Snout who didn't stay for a photo. It is still March...

Aplysia fasciata I think. Awesome Sea Hares and massive! Much more friendly than the normal ones who squirt purple liquid if you so much as look at them. #Guernsey #Intertidal #Marine

Andy Marquis @andym105.bsky.social · 02/02/2025

A couple of new species seen yesterday on the lower shore in Guernsey, got to use these big tides and nice weather! Seems like ages since we saw the sun! Liocarcinus corrugatus, the wrinkled Swimming Crab and Jewel Anemone. Both nice to see for the first time! #Guernsey #Marine #Intertidal

A search of leaf litter between Christmas and New Year, to fill in a gap on the map, provided several non-natives including Strumigenys perplexa and the tricky to ID Hypoponera eduardi. Outdoors in #Guernsey, 3rd location for the Hypoponera and 11th for the Strumigenys. #ants #hymenoptera

Andy Marquis @andym105.bsky.social · 05/01/2025

Any #beetle #Coleoptera folk around Bluesky? I think this keys towards Melinopterus sphacelatus but I am not certain. Could do better pictures if it wasn't moving so much... Found walking up a wall this morning near open farmland, #Guernsey.

Andy Marquis @andym105.bsky.social · 04/01/2025

This species is now plentiful in Guernsey, almost more so than other species combined in places.

130

Andy Marquis @andym105.bsky.social · 27/12/2024

Also found these in the same sample. Found 14 sieving litter so likely more I missed. Another new location, they are very much widespread. Strumigenys perplexa.

Andy Marquis @andym105.bsky.social · 27/12/2024

The things that appear in roadside leaf litter. This is going to be tough to get to species! Hypoponera/ponera sp. #Guernsey #ants

Andy Marquis @andym105.bsky.social · 22/12/2024

Found this in November in my lettuce which originated in Spain, so of course it's exciting to someone like me! Turns out to be Nesidiocoris tenuis which is new to the British Isles, just getting it added to the UKSI. They predate aphids etc so was probably trapped whilst eating its dinner...

Andy Marquis @andym105.bsky.social · 21/12/2024

I have now added studies of the Guernsey Odonata and Orthoptera, which covers quite a wide variety of species. The lists are now complete (I think), just need to add photographs which I will work on. www.guernseywildlife.co.uk/studies/index

Andy Marquis @andym105.bsky.social · 16/12/2024

Myrmica sabuleti lateral view of the head. I hope to be able to do some proper photographs of other small inverts in my collection over the winter. I am pretty sure I say that most winters so don't get too excited just yet! I have plenty of other work to be doing!

Andy Marquis @andym105.bsky.social · 15/12/2024

I will be adding the Orthoptera next as we check on the Guernsey species including the newest species added to the British Isles list in Summer '24 from a site in Guernsey, Tessellana tessellata, the Brown-spotted Bush-cricket. Bat detectors around the island suggest it may actually be widespread.

Just the one moth last night. Rusty Dot... I guess the migrants all went straight over Guernsey and didn't stop!

An enforced upgrade to my website means I now have a new site! My old package was out of date and no longer SSL supported so upgrade time. Now fixed and I have the backbone of pages back up and working again... Now comes the task of adding a load of photo's... www.guernseywildlife.co.uk

More ants... Messor capitatus were found on the #Guernsey cliff paths in July by Paul Brock and Andy Smith who were actually looking for another ant. I visited the area and observed workers carrying seeds back to the nest, protected by some major workers. The huge head and jaws apparent in images.

Andy Marquis @andym105.bsky.social · 28/11/2024

I'm hoping to do a bit more work on ants next year. Here are two Formica pratensis workers. One of the wood ant species, these build large nests on the #Guernsey cliffs. They are now extinct in the UK, so we are working to try and protect them.

The taxonomic biases in biodiversity data are growing over time. The amount of data we are collecting is growing, but the biases get bigger. We need to make a conscious effort to study the understudied! #SciComms #Science #Taxonomy 🧪 image from Troudet et al 2018 @natureportfolio.bsky.social

I also do some intertidal and marine work with the Pan-species hat on. I quite enjoy poking about in rockpools and under rocks. These photo's from a foray in October on Guernsey's west coast. There are of course marine insects to be found as well as all of the normal species you would expect.

Marine Carabid beetle Aepopsis robinii which live in rock fissures.

Green Ormer, similar to the better known Abalone

Marine Centipede Hydroschendyla submarina, here an adult protecting young, these are found from about mid-tide to extreme low water inter-tidally in rock fissures.

Some #moths from the cliff trap late October in #Guernsey. Nice to see different species by field trapping, garden traps tend to be quite similar. The weather suggests I might not be doing much more trapping this season, from experience the winter simply isn't worth the effort here.

Homemade Skinner Mk2 progress. Not wholly different to the Mk1 but with added stainless mesh to allow rain to drain if it rains in the night. Just need to fit the internal bits to rest the perspex and lights on now. #moths #lepidoptera #mothtrap
