A large, old grass heap with a green plastic sieve and a brown plastic tray and a pair of gardening gloves on the ground in front of it. The tray and sieve have bits of material from the grass heap in them.

A look down on the brown plastic tray where there are bits of material sieved from the grass heap and two small, reddish brown pseudoscorpions.

Close-up of one of the pseudoscorpions in the plastic tray, facing right with its large claws held out wide in front of it.

A good way to spend a Good Friday: find a good grass heap, do a bit of gentle sieving (panning for pseudoscorpion gold) and find a few good pseuds, in this case Lamprochernes nodosus. #arachnids #pseudoscorpions #invertebrates

One of my favourite arthropods. The pseudoscorpions turn up in sifted litter trays and stomp about with such attitude, even through they are so tiny!

A figure with a rucksack on their back, wearing a pale green coat and a grey peaked cap crouching down in woodland sieving moss onto a round tray. The ground is covered in fallen dead brown leaves but there are lots of patches of green grass pushing through in little clumps. There are bare trees in the background.

A tiny, shiny dark brown pseudoscorpion with dark reddish claws in the centre of a brown plastic tray amongst little bits of sieved moss, soil particles and plant debris.

Close up of the pseudoscorpion showing its robust rounded claws held out in front of it. The long oval body is shiny dark brown and clearly segmented. The head is also dark and shiny.

Took my trusty sieve with me when I cycled out to Ladybelt CP yesterday and managed to find a single Neobisium carcinoides - sieved from dry moss under a log (log carefully rolled back into position afterwards). #arachnids #pseudoscorpions

Searching a small dung heap in Long Melford (Suffolk) today produced my first self-found #pseudoscorpions (well, one). I believe this is Pselaphochernes scorpioides, but would certainly welcome the opinion of others.

@vannabartlett.bsky.social photographing a Common Chthonid pseudoscorpion (Chthonius ischnocheles) on the underside of an old tile.

While I looked for fungi, @vannabartlett.bsky.social managed to find a pseudoscorpion under an old tile in Denton churchyard, South Norfolk, on Thursday's bike ride.

#Pseudoscorpions

Two tiny pseudoscorpions amongst the debris of decaying wood. They have long 'arms' (the pedipalps or palps) that end in claws and pale oval, rather flattened bodies. The head and palps are reddish brown.

Close up of a pseudoscorpion amongst the debris of decaying wood. The head, pedipalps and claws are reddish brown and covered in short thick hairs (setae). The pale oval, rather flattened abdomen has rows of short setae across the segments.

Allochernes wideri confirmed new to Norfolk!
Found by a fellow county recorder; luckily I was present at the time and got to see them and take these photos.
Unfortunately, I now have to update my guide to pseudoscorpions in Norfolk...

A dark and shiny pseudoscorpion with pale reddish palps and claws facing right on a piece of wood.

I rarely find Neobisium carcinoides so it was a good job that the Norfolk beetle recorder was on hand at NWT Sweet Briar Marshes yesterday to find this one for me. Martin is far better at finding these critters than me! #Arachtober #arachnids #pseudoscorpions

I remember some years ago when I saw a little insect on my wall. I thought it had a weird shape, so I took a picture and magnified it. And it had arms with pincers, just like a tiny scorpion. 🦂 But it didn't have the tail. Turns out this is a pseudo scorpion. Never seen one since. #pseudoscorpions

A white plastic tray with some sieved straw debris in it and two small reddish brown pseudoscorpions in it.

Two reddish-brown pseudoscorpions in amongst some bits of straw debris. One has its claws pulled back against its sides while the other has them outstretched as it clambers underneath a bit of straw.

Two reddish brown pseudoscorpions sitting on some straw debris. The one on the left has its claws pulled back while the one to the right has them widespread in front as it clambers about.

Reached a bit of a milestone this week with these little beauties sieved from straw. Allochernes powelli, my 13th species of pseudoscorpion seen this year and I've now clocked up 100 records of pseudoscorpions in Norfolk for 2025.

A dark brown pseudoscorpion with reddish claws and chelicerae facing down on a piece of wood. The pedipalps are pulled back defensively to either side of the head.

The delightful church of St Mary at Barton Bendish with its thatched roof. Finding Chthonius ischnocheles on the underside of a piece of wood in a corner of the churchyard meant I'd ticked off another of my target 10 km squares for the week. #pseudoscorpions #arachnids #invertebrates

A flint church roofed in slate with it's tower gone - there is some metal fencing around the base of the tower remains and some brick rubble around it. There are two bicycles propped against the church and a figure in an orange coat next to one of them. The churchyard is mostly fairly short grass.

A pale brownish pseudoscorpion running over a pale stone with its claws spread wide. It is casting a dark shadow in bright sunshine.

Side view of a pseudoscorpion on a stone facing right. The left hand claw clearly has a 'dimple' on the hand which identifies the species as Chthonius tetrachelatus or Dimple-clawed Chthonid.

A lot of last weeks holiday in west Norfolk was spent cycling to churchyards to look for pseudoscorpions. I had three 10 km squares with no records so finding this Chthonius tetrachelatus under a stone at the base of the collapsed tower at Foulden helped fill in one of the blanks. #pseudoscorpions

Fabulous Large Tree Chernes (Dendrochernes cyrneus) found in west Norfolk last week while on holiday with @jeremybartlett.bsky.social Worth the windy weather and cycling in a thunderstorm to get to see these beauties! #pseudoscorpions #arachnids

A trip to the seaside on a Bank Holiday Monday? Yes please! Sand dunes at Titchwell yielded some lovely Dactylochelifer latreillii including my first nymph of this species of pseudoscorpion. #Pseudoscorpions #Arachnids

A luminous green caterpillar with a spiky tail horn is covered with the cocoons of parasitic wasps that have fed internally before emerging and spilling a cocoon attached to their host's back. Openings near the tops of the cocoons reveal that the adult wasps have emerged.

A luminous green caterpillar with a spiky tail horn is covered with the cocoons of parasitic wasps that have fed internally before emerging and spilling a cocoon attached to their host's back. Openings near the tops of some cocoons reveal that the adult wasps have emerged. The caterpillar is hanging from the leaf of a paw paw tree.

A brown inchworm caterpillar grips a leaf with its rear legs while a silken thread supports the head as it hangs upside-down. Half-a-dozen parasitic wasp cocoons dangle from the back of the caterpillar.

A crane fly with banded brown/tan banded legs and a yellow abdomen dangles from the leaf of a forest plant. Pseudoscorpions are attached near a joint on one meso- and one metathorasic leg. They use the fly to harmlessly carry them over the landscape (this phenomenon is called Phoresy).

Pseudoscorpion Chthonius ischnocheles on a reddish coloured bit of old roof tile. It has a dark brown cephalothorax and a paler brown abdomen. Its claws are pale reddish and fairly slender.

Pseudoscorpion Neobisium carcinoides on an old piece of roof tile which is covered in soil. The pseudoscorpion is dark shiny brown and its claws are quite stout.

Yesterday's Norfolk churchyard survey turned up trumps: a Chthonius ischnocheles under one old roof tile fragment & then a lovely Neobisium carcinoides under the next. First time I've found the latter species in a churchyard. Nice to compare the two together. #pseudoscorpions #arachnids

An old piece of wood showing signs of decay and with bits of soil stuck to it from where it has been lying on the ground. There are tiny two pseudoscorpions visible on it.
