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.

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).

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.

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!!!?

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...

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.

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... 🙂

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.

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.

@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.
August 14, 2025 at 3:50 PM
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!

If I sweep the grass in the meadow with a net, it is absolutely overrun with bugs, true bugs, as well as other things. This is, I believe, a Marsh Damsel Bug (Nabis limbatus). Females lay eggs in grass blades.

What's going on here, you 'mite' be asking yourself? (See what I did there?)

This female Mitopus morio harvestman is suffering the attention of no less than nine parasitic mites. Each is sucking out her haemolymph for its own benefit.

It's rarely only moths we catch in the moth trap.

Just yesterday we had a stonefly (Siphonoperla torrentium), a 10-spot ladybird, a Green Drake Mayfly, a Tipula species Cranefly, dozens of Caddisflies and thousands of midges!
July 10, 2025 at 12:42 PM
Another beautiful moth taken from the light trap yesterday. This one is called a Barred Straw.

These fly regularly at night from June to August, and the larvae feed on the Bedstraw family of wildflowers.
July 10, 2025 at 12:32 PM
Not a ladybird I see very often, and noticeably smaller than the 7-spot ladybird it superficially resembles. This is the 11-spot ladybird (Coccinella undecimpunctata). Try saying that three times, fast!

Like many other ladybirds, it feeds on aphids and is therefore beneficial to gardeners.
July 8, 2025 at 2:54 PM
Another beautiful moth which camouflages itself as a small broken twig. Much smaller than the Buff Tip I shared with you last week, this Flame Moth turned up in the moth trap this morning.

If you want an Order of insects that could absolutely absorb your entire life, you want moths. 🙂

Insects and invertebrates can be so hardy at times.

I took this Riband Wave moth from my moth trap this morning, and you can see that its left hind wing is almost cut in two. Perhaps it had a run-in with a bat or bird and somehow managed to survive.

It didn't appear to have any problems flying.
