No longer needed for farming, they remain part of the landscape’s story and, thanks to groups like the Yorkshire Wildlife Trust, are being restored as quiet havens for wildlife. Image courtesy of Yorkshire Wildlife Trust. See their article at www.ywt.org.uk/wolds-dew-po... 2/2

Our species taking spot #93 in our #YorkshireIn100Species series is the Brown China-mark moth, brought to us by Dick Shillaker. This moth has an intriguing life history, being one of only a small number of species with aquatic larvae! www.neyedc.org.uk/100-species/... 💧

Really cool story about long-distance pollen transport by migratory hoverflies. The actual research paper is here: doi.org/10.1111/1365...

This is the second time this year I have Parent Bugs breeding on Silver Birch locally in East Yorkshire. Is this just a chance finding or a known association @rockwolf74.bsky.social ?

Extensive bed of Fringed Water Lily Nymphoides peltata iin dried up part of lake near Hayton, East Yorkshire. 2nd September @teamneyedc.bsky.social

Could this be a Stigmella lemniscella mine in Elm? @vc28wildlife.bsky.social East Yorkshire 8 September

Weekend #Plankton Factoid 🦠🦐

...having had a look, the only aphid usually found on duckweed (Lemna spp.) is Rhopalosiphum nymphaeae (influentialpoints.com/Gallery/Rhop...), a species that host alternates between Prunus and a variety of water plants. These were mostly immatures.

Pick of the trap was this stunning Cosmopterix pulchrimella. A Pellitory-of-the-wall feeder & first discovered in Britain in 2001.

We caught some fantastic footage from a camera trap set up the night before our wildlife recording day in Hayton - a trio of otters! 🤩 We're recording wildlife in Hayton as part of the Live Labs 2 project, which you can read more about here: www.neyedc.org.uk/updates-insi...

Join NEYEDC & East Riding of Yorkshire Council in Hayton on Tuesday 2nd Sept for a wildlife recording day, part of the Live Labs 2 project! Alongside recording, we'll be hosting a moth trap opening, sharing what the project has found so far & showing how you can get involved: www.neyedc.org.uk/c2n 🔍

Burnished Brass, Roeslerstammia erxlebella, this am in Elloughton, East Yorkshire. Larva mines Lime leaves; lots of Limes close to this sighting. @doublekidney.bsky.social

Strange wee beasties on the Alnus cordata by the river, long horned moth or caddis, or something else entirely?

Salmon return to #Sheffield #TheOutdoorCity. News just in of the first record of breeding Atlantic Salmon in Sheffield for two centuries - open.substack.com/pub/abitblac...

A bit gruesome. Larva of parasitic wasp attached to 7-spot ladybird. Presume wasp is Dinocampus coccinellae; larva of this species emerges from inside ladybird, then spins cocoon & pupates under ladybird partially paralysed by wasp. This ladybird had been in same spot for several days.

Magnificent Alder on South Cliffe Common, SE Yorkshire. First blotch mine I think caused by Small Alder Midget. I dont know what caused the 2nd apparent blotch mine. Any thoughts welcome @vc28wildlife.bsky.social. Seen on recent @ynuorg.bsky.social excursion.

Could this Potamogeton be P. polygonifolius? Rather pointed leaves and in ditch bordering a sandy maize field (once heathland) and close to existing heathland (Hotham Carrs). 9 August @ astridbiddle.bsky.social. YNU VC61 excursion @ynuorg.bsky.social

Could this be leafminer damage in Buxus? East Yorkshire garden today @vc28wildlife.bsky.social

Flower-filled dikes attract bees: ‘Dikes are insect highways’ | EurekAlert! www.eurekalert.org/news-release...

🌱 River dykes are "insect highways" for wild bees 🧪 doi.org/pzns Dykes are a lifeline for bees. Researchers found nearly half of all Dutch bee species live on river dykes, with 10% being endangered red-listed species. #Botany #PlantScience 🧵 (1/10)

Four-barred Soldierfly, Oxycera rara. Found early yesterday morning on hedge only metres from a housing estate in East Yorkshire. It was not bothered by me moving the leaf to try to get a better photo (even so photos not that crisp, a pity).

Female Bog Bush-cricket, Metrioptera brachyptera, moulting, Strensall Common nr York 13 July. Spotted by sharp-eyed John K on Hull Nats field trip. @bladetail.bsky.social @ynuorg.bsky.social @teamneyedc.bsky.social

Surprised that iNaturalist proposed an ID for this single poor photo of a beetle larva: Broscus cephalotes. Found under log at bottom of dry valley in Yorkshire Wolds nr Londesborough 1st July. Could the ID be correct? @nottscoleoptera

Exposed chalky bank at Cleaving Combe nr Londesborough, East Yorkshire, 1st July. Nesting site for Blood Bees (species?) and Digger Wasps (species?) , with an active handsome White-palped Jumping Spider

Yesterday 30 June it recorded 32.1 C air temperature, a blistering 41.7 C grass temp. (imagine what that's doing to the flora/invertebrates), and the concrete temp. was so high (50+ C) that the sensor couldn't record it. Even at soil depths of 10 cm it was 29.5 C, and at 30 cm depth it was 20+ C.

Eriothrix rufomaculata with prominent eyes

I think this could be Chloreutis pariana , the Apple Leaf Skeletonizer, whose larvae particularly like to eat upper surface of Crab Apple leaves. Not too common in Yorkshire apparently. Found in East Yorkshire garden, nr Brough today. @doublekidney.bsky.social

The scavenger water beetle Hydrochus crenatus, categorised as Near Threatened in GB due to its highly restricted distribution. This species has a stronghold in Fenland drains and richly-vegetated pond margins, with records from around a quarter of the sites we sampled this week.

The story told within the industry is that until environmental assessment became a real thing in the late 80s motorways used to deliberately go through as much woodland as possible, because the land was cheaper.

Reminder: Nobel-prize winning PCR (1983), used in basically all genetic tech today, was only possible because of extremophile bacterium discovered in 1964 in Yellowstone funded by a small ~$80k NSF grant with no obvious application at the time. #science 🧪 www.richmondscientific.com/how-a-discov...

Hogweed in Helmsley (Yorkshire) hedgerow 12 June had lots of shiny green nymphs. Assumed they were Grypocoris stysi as adults present. Are holes in umbel buds anything to do with them? @rockwolf74.bsky.social

I have no idea what this is? 4 mm long, although it could be double this because it gave the appearance of being bent over . On Laurel hedge in East Yorkshire 9th June. Can anyone help with ID, please. @andydnunn.bsky.social

I think this is a Giant Aphid, Lachninae. East Yorkshire garden today. Does not seem to fit Giant Willow Aphid because of lack of dorsal 'horn'. Anyone thoughts on the species?

It's Zig-zag season again in East Yorkshire. Seen on Elm leaves 31 May, the characteristic leaf damage caused by one or more larvae of the sawfly Aproceros leucopoda feeding on the leaf. This sawfly species was first recorded in Yorkshire in 2021. @suillia.bsky.social

Colourful insect highlights from Leconfield DST bioblitz, East Yorkshire, 25 May

Spotted crawling over paving today, East Yorkshire. Put on grass for photo. May be a a Large Yellow Underwing but why are the wings so short? Any thoughts? @andydnunn.bsky.social @doublekidney.bsky.social @scarpermac.bsky.social

Blotch mines on Laurel leaf, East Yorkshire today. On the underside empty pupal cases can be seen. No mention of blotch mines on Laurel on British Leafminers website. Anyone have a suggested ID? @andydnunn.bsky.social

Just wondered if anyone could shed light on these "leech" like creatures that were attached to a branch in my local river ? There were hundreds, all about 10mm or so long.

Nettle Weevils (Phyllobius pomaceus) Kilnwick, East Yorkshire, 13 May.

This impressive large spider crossed the pavement in front of me early this morning, Elloughton, East Yorkshire. Pavement next to an extensive old wall. I think it could be the Black Laceweaver Amaurobius ferox @ecology-digest.bsky.social

Birch leaf Elloughton East Yorkshire, today. I had thought these were blotch mines with exit holes. I now think they are feeding signs of case-bearing moth caterpillar eg Coleophora. Assume holes are where caterpillar was attached and feeding. Do you agree @andydnunn.bsky.social
