F for Fun Fact. Floronia bucculenta is the only UK native spider who's scientific name starts with F (I hope!) F is the Feather Legged spiders, Uloborus plumipes (pic) Usually found in garden centres. Uloborus walckenaerius, found only at a few S.Eng sites. #Arachtober @britishspiders.bsky.social

#Aractober day 5 is E for Ero. Often referred to as pirate spiders due to the habit of invading the webs of other spiders where they prey on the occupant. E furcata/Cambridge I have two abdomen tubercles. E tuberculata/aphana have four. The egg sacks are also quite distinctive.

Tegwyn @arachnoteg.bsky.social · 04/10/2026

Dysdera, the woodlouse spiders. #Aractober. Also know as the Baked Bean spider 😁D.erythrina and D.crocata, the one you will most likely come across. The large chelicerae and bright orange/red colour make them very distinctive. @britishspiders.bsky.social

#Aractober Decided to feature two C's today with plenty to choose from. A cute jumping spider Calositticus inexpectus. Also a tiny 1-2mm spider that spins webs less than 8mm in size. You will only find it in a few garden centres and botanic gardens, Coleosoma floridanum.

020

Tegwyn @arachnoteg.bsky.social · 02/10/2026

Badumna longinqua for today's A-Z. New to the UK and probably spreading through plant trade. Check out your local garden centre, B+Q and especially B+M stores outdoor plant areas. You will likely find the distinctive web before any spider. Visit the BAS on YouTube for more info. #Aractober

Tegwyn @arachnoteg.bsky.social · 01/10/2026

#Aractober Didn't participate last year due to circumstances. Usually I challenge myself and daily find a different spider to post. Not practical this year so going for an A-Z challenge. Easy to start Araneus diadematus, Garden Spider. Lots of gravid females this time of year. Comment your A

Tegwyn @arachnoteg.bsky.social · 23/09/2026

Some spiders from the last few days. Anypheana numida, Liocranum rupicola the Pied Stone spider and Parasteatoda spiderlings, P.tepidariorum? Also possible new site for what is likely Helpis. For size it has a small fruit fly. @britishspiders.bsky.social @tylanberry.bsky.social @sewbrec.org.uk

Tegwyn @arachnoteg.bsky.social · 17/08/2026

Seems to be Spitting spider season (check out the BAS Atlas). Indoors this time. Not unusual for me to see two or three over a week or so and then nothing for months, or even until the next year. @britishspiders.bsky.social

1143

Tegwyn @arachnoteg.bsky.social · 15/08/2026

A carefully suspended and disguised egg sack constructed by Cryptachaea blattea. A introduced species that's gradually becoming wide spread since being first recorded in 2011. @britishspiders.bsky.social @cofnod.org.uk

042

Tegwyn @arachnoteg.bsky.social · 15/08/2026

A little search around the garden produced this female Spitting spider, Scytodes thoracica, keeping care of her eggs. This is one of our six eyed spiders and has an unmistakable shape. Uncommon but S.Wales is one of the regions you can find it @britishspiders.bsky.social @sewbrec.org.uk

0133

Tegwyn @arachnoteg.bsky.social · 06/08/2026

A very messy Nigma puella Bleeding heart spider retreat with multiple egg sacks. Have seen females at times mostly green or even redish in colour rather than the typical white. @britishspiders.bsky.social

031

Tegwyn @arachnoteg.bsky.social · 05/08/2026

Anyphaena numida one of the not so common buzzing spiders. It's juv. but feeling confident! I first recorded (2) in Aug 2022 Penarth, think the first Welsh record. This one yesterday was from a few miles away in Cogan and only the 2nd time I have seen it. @britishspiders.bsky.social @cofnod.org.uk

2102

Tegwyn @arachnoteg.bsky.social · 02/08/2026

1/2Helpis occidentalis egg sacks. Spent a few interesting hours with R.Gallon Saturday.

Tegwyn @arachnoteg.bsky.social · 31/07/2026

The grass/stone bank line produced lots of spider igloos under the stones near areas with ant activity Zodarion fuscum. Most igloos had egg sacks, some were being used by imm. salticus. Recorded here previously, the third different location I have come across it locally. @britishspiders.bsky.social

Tegwyn @arachnoteg.bsky.social · 31/07/2026

A very quick visit to Porthkerry with plenty of Argiope bruennichi Wasp spiders. Would like to find a male at some point.

020

Tegwyn @arachnoteg.bsky.social · 30/06/2026

Able to photograph H.pluchei and her spiderlings that emerged yesterday. Lots of eyes and legs! Certainly a nightmare for anyone who is arachnophobic. Recorded in Britain since 2004 and looks to be now established at a new site in #Wales @britishspiders.bsky.social @sewbrec.org.uk @cofnod.org.uk

2145

Tegwyn @arachnoteg.bsky.social · 28/06/2026

Neottiura bimaculata, Cream-backed Comb-footed spider. Just the one British species but considered regionally abundant. I rarely see it, usually in gardens, and still yet to find a male. This one is carrying her carefully made egg sack and safely released. @britishspiders.bsky.social

1124

Tegwyn @arachnoteg.bsky.social · 20/06/2026

Found it difficult to get pictures of this 1-2mm Theridiidae. Coleosoma floridanum a tropical glasshouse species in the UK and ant mimic. Lots of mature males/females. Appears to be a first record for #Wales with only a few in the UK. @britishspiders.bsky.social @cofnod.org.uk @sewbrec.org.uk

0123

Tegwyn @arachnoteg.bsky.social · 13/06/2026

Visit to a garden centre I haven't looked around in before produced two Marpissa muscosa and a Holocnemus pluchei. I know not many records in my VC41 for either. Went to check but the BAS ATLAS has an 'elasticsearch' error. @britishspiders.bsky.social @cofnod.org.uk @sewbrec.org.uk

2266

Tegwyn @arachnoteg.bsky.social · 08/06/2026

A spider I have been hoping to find for a while and an addition to my personal list. Liocranum rupicola, Pied Stone Spider, nationally scarce but locally distributed in south #Wales @britishspiders.bsky.social

2113

Tegwyn @arachnoteg.bsky.social · 04/06/2026

Photos related to my previous post. You can make out the engulfed spider and just about see some of the fungus structure (conidiophores and the Aspergillus-like heads?) @britishspiders.bsky.social @cofnod.org.uk @britmycolsoc.org.uk 2 Mature male N.celullanus nearby, the possible spider victim sp.

051

Tegwyn @arachnoteg.bsky.social · 23/05/2026

At a friend's house yesterday and pleased to find a rubbish spider. More like rubbish pics tbh! Cyclosa conica or Trash Line spider. Wikipedia says it has no common name if anyone wants to update it. This one is the regular var. if the others are still recognised as so. @britishspiders.bsky.social

063

Tegwyn @arachnoteg.bsky.social · 19/05/2026

A spider worth looking out for at your local garden centre. Holocnemus pluchei the Marbled Cellar Spider. Very different in appearance from the common Pholcus phalangioides. Pos' a population locally as multiple spiders of various sexes. Would you say sub adult pictured? @britishspiders.bsky.social

0104

Tegwyn @arachnoteg.bsky.social · 15/05/2026

Thought I would share this nice looking wolf spider/Pardosa from today. @britishspiders.bsky.social

0134

Tegwyn @arachnoteg.bsky.social · 08/05/2026

Got me looking now. Mating pair from a few years ago.

121

Tegwyn @arachnoteg.bsky.social · 08/05/2026

Caught this Micaria that was speeding across the shed and investigating every crack. General appearance looks like typical M.pulicaria. Managed a live epigne shot. Looks M.p rather than M.micans to me but not confident. Good enough for an ID? @britishspiders.bsky.social @tylanberry.bsky.social Ta

131

Tegwyn @arachnoteg.bsky.social · 28/04/2026

Spotted this adult female Ero aphana in Barry. A nationally scarce spider and appears to be the third record for VC41 Glamorgan. The other two I have managed to find were in Penarth. @britishspiders.bsky.social @sewbrec.org.uk @cofnod.org.uk @tylanberry.bsky.social

2186

Tegwyn @arachnoteg.bsky.social · 26/04/2026

Nice time at Crymlyn Bog NNR organised by @wtsww.bsky.social. Plenty to see and came across this Leopard bear spider, Arctosa leopardus @britishspiders.bsky.social

2174

Tegwyn @arachnoteg.bsky.social · 17/04/2026

Agreed. Not 1700's, also no spiders, but I have a 1912 (1st 1887)edition of The Young Collector - Ants,Bees,Dragon-Flies,Earwigs,Crickets, and Flies. The writing style is great. Particularly like the section on Pulex irritans. "Familiar to every one" sounds so casual and everyday but also personal.

010

Tegwyn @arachnoteg.bsky.social · 17/04/2026

From a sit and think in the garden during a brief moment of sunshine. Anelosimus vittatus and a nicely coloured Zebra jumping spider @britishspiders.bsky.social

1134

Tegwyn @arachnoteg.bsky.social · 14/04/2026

Nice. Guess it lives up to it's name. Seived from deciduous leaf litter as you say. Been a while since I looked at a liny, forgot to check both the sites I use! Thanks 👍

020

Tegwyn @arachnoteg.bsky.social · 14/04/2026

Any suggestions? Best photo I have with this 2mm liny'. Simply not clear enough for me to ID. Woodland habitat, reddish legs. Hopefully someone can recognise the mantis shape. If not will keep for it for when I have better scope. Ta @britishspiders.bsky.social @tylanberry.bsky.social @cofnod.org.uk

173

Tegwyn @arachnoteg.bsky.social · 06/04/2026

Pleased to find my first ever of these unusual Opiliones/harvestman. Looks like Anelasmocephalus cambridgei. Found vacuum sampling around the base of a small group of coniferous trees. One for @megabunus.bsky.social ID confirmation if possible please @britishspiders.bsky.social @sewbrec.org.uk

191

Tegwyn @arachnoteg.bsky.social · 02/04/2026

Spotted this interaction with a spider (Amaurobius) and a Ichneumon (stramentor?) Fortunate escape for the wasp after what looks like poking the spider in the face and possibly distracting it with the yellow dot. @britishspiders.bsky.social @sewbrec.org.uk

262

Tegwyn @arachnoteg.bsky.social · 28/03/2026

A spider that's relatively easy to find in damp woodland in my locality, usually under stones. I think these have a nice colour tone and pattern. Coelotes atropos.

060

Tegwyn @arachnoteg.bsky.social · 21/03/2026

The Australian Helpis sp. have survived the winter. Managed to find three. An adult female, probably immature female and a juvenile. My thanks to the manager Rebecca for giving me permission to roam about. @britishspiders.bsky.social

151

Tegwyn @arachnoteg.bsky.social · 21/03/2026

Not seen one before so ID confirmation appreciated. My first Marpissa muscosa, Fencepost Jumping Spider, male. A nationally scarce spider. Again looks like the 2nd record for Glam VC41, the previous being 2015. @britishspiders.bsky.social @cofnod.org.uk @sewbrec.org.uk

1165

Tegwyn @arachnoteg.bsky.social · 21/03/2026

From my next few posts guess what habitat I visited. Holocnemus pluchei, the Marbled Cellar Spider. Found six of them all grouped close together. Only the 2nd record for Glamorganshire VC41 (and Wales?) @britishspiders.bsky.social @cofnod.org.uk @sewbrec.org.uk

0115

Tegwyn @arachnoteg.bsky.social · 14/03/2026

Some jumpers on the shed today enjoying the sunshine. Only seem to see Heliophanus, Sun jumpers, in the garden during early spring. Zebra enjoying a Philodromus and what is likely a tiny juv. P.lanigera @britishspiders.bsky.social

Zebra jumping spider eating it's spider prey

0114

Tegwyn @arachnoteg.bsky.social · 01/03/2026

@cofnod.org.uk will undoubtedly have a few suggestions. My contribution is Kryptonesticus eremita. Currently only known in the UK from a disused mine entrance on Flat Holm island and a Penarth sewer chamber.

0124

Tegwyn @arachnoteg.bsky.social · 21/02/2026

Due to various circumstances I have not had any trips out looking for spiders so far this year! Fortunately I have been looking after some spiders that have kept my interest. Not had anything to personally post so decided to share some pictures of local spiders from previous years.

0143

Tegwyn @arachnoteg.bsky.social · 30/01/2026

Badumna longinqua. This time B&Q Culverhouse Cross. On the frame of the auto doors in the garden section. Webs scattered about the place. @britishspiders.bsky.social @sewbrec.org.uk

1153

Tegwyn @arachnoteg.bsky.social · 23/01/2026

@chalkspring.bsky.social you were right, mature male! Can't get decent palp shots atm. Can clearly see the chelicerae teeth that seem to be part of the ID process when I get to do it properly. @britishspiders.bsky.social

050

Tegwyn @arachnoteg.bsky.social · 22/01/2026

Nice call. Some more camera shots, not clear but what do you think?

010

Tegwyn @arachnoteg.bsky.social · 22/01/2026

Update on the group of Helpis I found in Nov. They have gone through a few moults. Female is now mature. More by luck than anything else the other one turns out to be a male. Still looks immature to me. Will do both ID's when male has matured.

1112

Tegwyn @arachnoteg.bsky.social · 29/11/2025

Are you particularly looking for A.barbipes records atm? Have recorded them from two different locations nearby. Very nice looking spider.

130

Tegwyn @arachnoteg.bsky.social · 26/11/2025

What appears to be a Helpis sp. Found several spiders varying from spiderlings to approx 4mm in size. Currently rearing two until maturity for definite ID. Readily taking fruit flies. @britishspiders.bsky.social @tylanberry.bsky.social @cofnod.org.uk
