Wasp Spider
Argiope bruennichi) is a species of orb-web spider distributed throughout central Europe, northern Europe, north Africa, parts of Asia and in the Azores archipelago. Like many other members of the genus Argiope, (including St Andrew's Cross spiders), it shows striking yellow and black markings on its abdomen.
The spider builds a spiral orb web at dawn or dusk, commonly in long grass a little above ground level, taking it approximately an hour. The prominent zigzag shape called the stabilimentum, or web decoration, featured at the centre of the orb is of uncertain function, though it may be to attract insects.
When a prey item is first caught in the web, Argiope bruennichi will quickly immobilise its prey by wrapping it in silk. The prey is then bitten and then injected with a paralysing venom and a protein dissolving enzyme.

The male of the species is much smaller than the female. It can often be seen in or near a female's web waiting for her to complete her final moult, at which time she reaches sexual maturity. At this time her chelicerae (jaws) will be soft for a short time and the male may mate with the female without the danger of being eaten.

In 2008 Aidan Grady, Christie van Tinteren and Matthew Secombe were responsible for the discovery of well over 100 of these spiders. The colony was later discovered to be the largest found in the UK. The team worked with Plymouth University and the RSPB to catalogue the discovery and learn more about the spiders. Sir David Attenborough said that the discovery was remarkable.

Ladybird Spider Eresus cinnaberinus (formerly Eresus niger), of the family Eresidae. Despite it has a new name, the taxon "Eresus cinnaberinus" is considered a nomen dubium by some authors. The specimens having been divided into the species E. kollari, E. sandaliatus and E. moravicus. The three species differ in size, colour pattern, shape of prosoma and copulatory organs, and habitat, with no morphologically intermediate forms. As eastern and western E. kollari are genetically different, with the eastern form likely a hybrid between "pure" E. kollari and E. moravicus, it is possible that later revisions will partition it into additional species.

Males are up to 11 mm long, females can reach up to 20 millimetres (0.79 in). Males have a black prosoma and a strikingly red opisthosoma with four black dots (sometimes with white lining), resembling a Ladybird. The back legs have white stripes, the hind legs are partly red. Females are black with some white hairs, only the front is sometimes yellow.

It prefers sunny, dry locations. These spiders live in up to 10 centimetres (3.9 in) long underground tubes with a diameter of about one centimetre. On top they are much wider and lined with cribellate silk. Many webs can usually be found in the same place, sometimes up to ten on a single square metre. E. cinnaberinus mainly catches millipedes and beetles. Males walk around during September, searching for females. If it finds one, it lives with the female in her tube, and they feed from the same web.

This spider is classified as endangered in Great Britain. It is given full protection under Schedule 5 of the Wildlife and Countryside Act 1981. Reintroduction is in progress at the Arne RSPB reserve in Dorset, England. In Poland and Germany it is also considered endangered.
