#Psyllids
This hackberry (Celtis occidentalis) came in today with galls. The immature psyllids inside don't even look real!

Striated Pardalote.

This is a small, common Australian bird known for its subtle colors, noisy calls, and acrobatic foraging high in eucalyptus trees, where it eats insects like psyllids and their lerps, helping control tree pests. Often heard more than seen.

I have updated the @norfolknats.bsky.social species guide to Norfolk Psyllids, which is available to download from the NNNS website here: norfolknaturalists.org.uk/wp/wp-conten... It now covers 60 species (about 3/5 of the British list) so is hopefully of use even for those outside of Norfolk.

New paper! A long overdue update with the first identification guide to the non-native psyllids of Hawaii. 🧪 🦋
🌿 An updated checklist of twenty-three non-native jumping plant lice was established for the Hawaiian Islands, including the formal description of a new species originating from Australasia.

Aylsham today. Zebra Spider (Saltus scenicus), Green Mesh Web Spider on the Ivy (Nigma walckenerai), Another Bay tree, more Bay psyllids (Trioza alacris) & Large Sow Thistle Aphid? (Uroleucon conchi) @norfolknats.bsky.social

Swirlix: small, round, covered in sweet, sticky white "fur" which has been described as being like cotton candy.

In conclusion: Swirlix is actually a giant psyllid - the white "fur" is its lerp.

The @norfolknats.bsky.social species guide to the Psyllids of Norfolk has now been updated with 2024 data (251 records of 32 species - thanks to all who have submitted records). There are also new photos for Cacopsylla visci & Trioza chenopodii. norfolknaturalists.org.uk/wp/wp-conten...

Super fun collaboration with Diana Percy and Patrick Degnan.

@hansenlab.bsky.social et al. study the evolution of bacterial symbionts of Pariaconus psyllids in Hawaii, demonstrating that island biogeography and host plant ecology shape symbiont losses and codiversification patterns.

Been a while since I went to the big box garden store AKA the Agricultural Pest Zoo. I took the caterpillars home of course

Psyllids are active again in Ash causing leaf curl, which goes a pink/ red colour
I’ll breed some out to check the species.
@norwichbirder.bsky.social has a brilliant guide to this group

First attempts at drawing psyllids. These are odd looking bugs. Working from reference photos is OK if you have a good knowledge of the anatomy of what you are drawing. Psyllids are new to me so I really need a specimen as well to work out how they go together.

I've started to see a few more adult psyllids around recently. These ones are Trioza urticae, the only UK species associated with nettles, and when present often relatively easy to spot. The colouration (dark above and below with pale greeny-yellow sides) is typical. #NorfolkPsyllids

You gotta love a lerp!

Lerps are the intricate protective cover secreted by tiny insects called psyllids. They are often maligned as ‘pests’ when they are actually a really important part of an area’s biodiversity.

This one was found on a planted Eucalyptus botryoides in St Kilda, Victoria.

Have you ever looked under dandelion leaf? You might see there hairy 1-2mm nympfs of Trioza dispar, a species of psyllids.

🧬 A comprehensive DNA barcoding study of Chinese parasitoid wasps has revealed diversity among encyrtid species that attack psyllids, with molecular analysis identifying 32 distinct species previously difficult to distinguish through morphology alone. Full study: doi.org/10.3897/jhr.99.202665

My downloadable species guide & atlas to psyllids in Norfolk is now available on the NNNS website here: norfolknaturalists.org.uk/wp/wp-conten... This is a follow up to the article in NNNS Transactions with more pictures, ID tips etc to complement existing ID resources.

The #Weebill plays an important role in the #Australian ecosystem by helping control populations of sap-sucking insects like scale insects and psyllids.

Some psyllids from Norwich cathedral herb garden this afternoon - a mating pair of Arytaina genistae on Broom, Trioza alacris on Bay and Spanioneura fonscolombii from Box. #NorfolkPsyllids

My lemon tree has been living inside a mesh cage since 2021 and yet there are asian citrus psyllids partying on it right now as we speak.

Our preprint is now live! We have sequenced the genomes of three psyllid species. These insects pests transmit devastating plant diseases like 'zebra chip' in potatoes and 'carrot yellows' in carrots. 🥕

Quite a few Norfolk county recorders are already on Bluesky, including @norfolkmoths.bsky.social (moths), @andymus.bsky.social (sawflies), @tim-hodge.bsky.social (hoverflies), @vannabartlett.bsky.social (harvestmen), @applewildlife.bsky.social (lacewings) and @norwichbirder.bsky.social (psyllids).
