#RecordOfTheWeek today is a Portuguese Man'O War (Physalia physalis) spotted in Llangennith by Phillippa Davies, washed by after last week's storms. This species is not actually a jellyfish, but a colony of small creatures called zooids. Many thanks for record & pic, submitted via LERC Wales App.

Cofnod #RecordOfTheWeek is this adult Marble Gall Wasp (Andricus kollari) recorded by KevinH on Mynydd Mawr. More used to seeing the actual galls on Oak, than adult. @sewbrec.org.uk @wwbic1.bsky.social

My old Orthoptera video is getting some traction on YouTube atm (thanks random algorithm!) so thought it was a good time to share here. I need to update to add Grey Bush-cricket and some Oak Bush-cricket footage (and improve audio quality 😁) #TeamOrthoptera youtube.com/watch?v=mjmt...

I'm doing an online talk on 16/09 about my MSc thesis, which was all about iNaturalist data for invertebrates in the UK, and the alarmingly high proportion of it which 'falls through the cracks' due to data quality concerns. Please join if interested! Link: www.eventbrite.co.uk/e/falling-th...

It’s not just plants that photosynthesise! Solar powered sea slugs get their names from eating the chloroplast in algae, which lets them use photosynthesis as a source of energy. Sea slugs that do this are called “sacoglossans” and are often a vivid green colour. 💚 #NationalMarineWeek 📷 Dan Bolt

Quite possibly nudibranchs are the best thing EVER! Read all about a trip to Anglesey here... analternativenaturalhistoryofsussex.blogspot.com/2025/07/plan...
