Agelena labyrinthica (family Agelenidae)

This is a very common spider in open countryside, hedgerows, roadside verges with grass banks etc. It builds a large sheet web with a prominent retreat amongst grass or other low vegetation.



Eratigena sp. (family Agelenidae)

The taxonomy of this genus is still being debated. Some believe this should be called Eratigena atrica.




Amaurobius sp. (family Amaurobidae)

There are three Amaurobius species in the UK. This one is probably similis but to be sure of an ID it's best to examine them under the microscope.



Amaurobius ferox (family Amaurobidae)

I have found several A. ferox in my garden but, as yet, it is the only place I have found this species. This one was in one of my compost heaps. It's somewhat darker than other Amaurobius species.




Anyphaena accentuata, buzzing spider (family Anyphaenidae)

A medium sized spider with a characteristic mark on the abdomen. I have only found them on tree trunks. They apparently make a buzzing noise, but I've not heard this.




Atypus affinis, purse web spider (family Atypidae)

I have found purse web spiders, or their webs, on a few sites now. They live in a long sausage-like web which lies partly above ground and partly underground. When an insect walks over the above ground part the spider grabs it and pulls it inside the web. The first one I saw was an adult female walking along a path on a sunny day, which was unusual as females normally stay (and die) inside their purse webs.

Dysdera sp. (family Dysderidae)

Of the two UK Dysdera species D. crocata is the more common. It is found under stones, logs etc. and is often found around houses, like the one photographed.



Harpactea hombergi (family Dysderidae)

A common species that I've come across in a variety of habitats - tree trunks, woodland leaf litter, walls of houses etc.




Trachyzelotes pedestris (family Gnaphosidae)

I found the spider in the photo scurrying across the ground on heathland. It's a species I see only occasionally, but it's not rare.



Scotophaeus blackwalli (family Gnaphosidae)

A common species around my house, inside and out, and in the garden. It can often be found by walking around the garden at night with a torch.




Ero aphana (family Mimetidae)

Ero species prey upon other spiders, mainly theridiids, by creeping up on them slowly and biting them on the leg. E. aphana was first recorded in Suffolk as recently as 2011 but a few more have been found since.



Ero tuberculata (family Mimetidae)

I have only found Ero tuberculata on one heathland site and, even there, have only found two. It's leggier than other UK Ero species.




Philodromus cespitum (family Philodromidae)

There are several Philodromus species in the UK and some are similar and so difficult to distinguish. The spider in the photo was put in a spy pot and its epigyne examined under the microscope, which allowed me to identify it as P. cepsitum, one of the more common species. Then it was set free.



Tibellus sp. (family Philodromidae)

There are two Tibellus species in the UK and microscopic examination is required to determine which an individual spider is. T. oblongus is common in drier habitats, particularly where there is thick grass, whilst maritimus is found in wet habitats.




Dolomedes plantarius, great raft spider (family Pisauridae)

Its common name was probably acquired because it is often seen sitting on vegetation around the edges of pools. Dolomedes plantarius is an impressively large spider and somewhat variable in appearance, with plain and striped versions. The nearest site I can find it on is Redgrave and Lopham Fen, where numerous deep pools have been dug to enable it to survive during droughts. I did some observations on it there in the 1980s (written up in the Transactions of the Suffolk Nat Hist Soc)



Pisaura mirabilis, nursery web spider (family Pisauridae)

A very common species, in hedgerows, woodland egdes etc. I even find them in my garden occasionally. The one in the photo is a female carrying an egg sac. She will eventually build a nursery web to protect the egg sac and, later, the spiderlings when they hatch.




Segestria senoculata (family Segestridae)

This Segestria was found on the trunk of a tree in a wood, a common habitat for the species.




Zora spinimana (family Zoridae)

Zora spinimana is a common spider amongst thick grass
