Ireland's Incredible Invertebrates!

I've been working on building this app over the last month or so. If you're interested in biological recording, you might like it. It does cost (€4.99 a month), but just enough to cover the server costs. Works on mobile and desktop.

Would love to hear what you think? bionexus.pro

Me signing my name for the community members of DeafVillageIreland.ie while the amazing Caroline O'Leary looks on.

I had a fantastic experience yesterday, as I was invited to DeafVillageIreland.ie to talk to the deaf community members about Irish bees. I've never felt so welcome nor witnessed so much interest in my talks.

Special thanks to Caroline (who also invited me) and Aoife for signing my talk.

A pseudoscorpion feasting on a bark louse

Serendipity allowed me to catch the exact moment a tiny (1.5mm) Chthonius ischnocheles pseudoscorpion caught and ate a bark louse (Psocoptera).

For some reason, I assumed it would use its palps (pincers) more, but it didn't. It just chomped away with its chelicerae (jaws).

Artioposthia exulans, a terrestrial flatworm

Meet Artioposthia exulans
This flatworm specimen was sent to me to photograph and share it with you all. A non-native visitor to this island, it seems to be located primarily in the south-west and most likely arrived on horticultural goods, once again, highlighting the importance of biosecurity.

Mitostoma chrysomelas harvestman

I was out surveying today, Blessington lakeside, and turned a stone only to find not one but two really scarce harvestmen (and you know I liove my harvestmen).

The last time Mitostoma chrysomelas was recorded in the Republic of Ireland was way, way back in 1997.

Isn't it a little stunner!!!?

A Torymus species wasp laying an egg

Last chance to grab a ticket to this evening's webinar, The Weird & Wonderful World of Irish Wasps.

I promise you some mind-blowing facts and anecdotes.

It's only 2mm long. You wouldn't even know you'd licked it. 🤣

Yessssss!

Plus, even though they have legs, they seem to float along.

A pseudoscorpion on a white background

There's very little that matches the excitement of finding a pseudoscorpion for me. They are so few and far between that they always warrant a mini celebration.

This stunning specimen is Chthonius ischnocheles (get your tongue around that!).

Have you ever seen a pseudoscorpion? Let me know...

Thanks, Steph. And, can I just say that I have built two beetle boxes in microWild based on your thesis!!!

100% agree, and one thing I didn't mention is the potential for new species to carry diseases which they may be immune to, but which can affect other species or fauna, which is why biosecurity is so important.

https://www.gbif.org/species/2203739 A distribution chart showing A. nasatum's distribution in European countries.

No. They are detrivores, like all the other woodlice in Ireland. There is plenty of dead leaves and rotting wood to go around. They aid in the decomposition and return of nutrients to the soil.

Most likely, it hasn't spread more because our climate just isn't suitable, but that is changing...

A really exciting find for me this weekend in my parents' front garden.

Say hello to the Nosy Pill Woodlouse, Armadillidium nasatum.

This is the first record of it in the wild in Ireland (i.e. outside of a garden centre). Keep an eye out for strange things; you never know what you'll find.

Every field surveyor's worst nightmare.

This is an adult tick (Ixodes ricinus).

Photo 1: Dormant
Photo 2: It smelled my breath or felt the heat of my finger using special organs (Haller's Organ) on its forelegs and started to wake
Photo 3: It tried to give me a hug 😬

Amazing creatures.

A 2mm long jumping spider sitting on a stone

This is the tiniest little jumping spider I came across yesterday while surveying my parents' front garden.

I know it's anthropomorphic, but jumping spiders always look a little worried to me. I want to help them, but I'm not quite sure how... 🙂

Vanna got there first! :)

The face of a brown hawker dragonfly

This is the business end of a Brown Hawker Dragonfly. If you are a flying invertebrate, you do not want to see this up close.

Dragonflies are exceptional on-the-wing hunters with a success rate that is unmatched in the animal kingdom.

I know there are a few that look similar. But if it came off a Nettle then it might be this one... :)

A white crab spider sitting on a thistle flower head

Last spider pic for a while, I promise... 👀

This beautiful Flower Crab Spider (Misumena vatia) was spotted hiding out on some Thistle flowers, waiting for an unsuspecting meal. We saw it eye up an Eristalis tenax (Drone Fly), but it opted out as the fly was quite large.

Meta menardi (Cave Spider)

@collieennis.bsky.social and I went on a special adventure yesterday, including checking on a population of Cave Spiders (Meta menardi). Hunched over, walking down a smelly underground tunnel and trying desperately to avoid badger poo, I eventually got face-to-face with this stunning specimen.

Trochosa species spider

Just look at this beautiful Trochosa species spider, found under a granite rock, lakeside in Valleymount, West Wicklow. These are bigger than your average wolf spider!

You might not tolerate them, but unfortunately it does seem as if they are here to stay. They are just everywhere, and you can see real deficits in other native arachnids where they are present.
