Photographer's Note

Pauk osa dobio je naziv po crnim i žutim (i belim) šarama na trbuhu ženki zbog kojih liči na osu. Mrežu plete u travi ili žbunju, živi usamljeno i hrani se insektima. Ženke su veće (25 mm) od mužjaka (7 mm). Mali, svetlo braon mužjak u jednom delu mreže čeka pogodan trenutak za parenje, a to je vreme nakon poslednjeg presvlačenja ženke.
Pauci uopšte, poseduju otrovne žlezde, smeštene u osnovi helicera (usneni ekstremiteti) čijim sekretom ubijaju plen. Kada insekt uleti u mrežu, pauk ga veoma brzo obavije paučinom, otrovnim helicerama ga usmrti, a zatim u njegovo telo ubacuje crevne sokove, koji vare mekane delove insekta. Zatim pauk usisa svarene delove tako da u mreži ostaje samo prazan hitinski omotač insekta.
Za pletenje mreže pauci imaju na trbuhu paučinaste žlezde što luče lepljivu materiju koja se na vazduhu brzo stvrdne. Pletenje mreže pauk obavlja na vrlo složen način i postoje više tipova mreža, u zavisnosti od vrste pauke. Takođe, u slučaju zamene mreže, pauk pojede svoju staru mrežu da bi iskoristio proteine iz nje.

Argiope bruennichi, or the wasp spider, is a species of orb-web spider distributed throughout central Europe, Northern Europe, north Africa and parts of Asia. 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.
The largest recorded colony of this species found in Britain was first discovered by Aidan Grady and Christie van Tinteren, who were joined by Piran Blyth, Matt Secombe and Kai Johnson. Their count currently totals nearly 100. At a later date Sir David Attenborough said how exciting it was that the team had made such a rare discovery. The team are now working in co-operation with the wildlife trust to try and conserve this huge colony. (Written 3/9/10)
During Summer 2006, research was carried out in the UK to find that there has been an influx of these spiders to the UK. The colour is still similar, although the yellow stripes are a bit more cream coloured.[citation needed]
This species of spider was featured in the Movie Eight Legged Freaks as the main species antagonists
There is one subspecies currently recognized:
Argiope bruennichi nigrofasciata Franganillo, 1910 (Portugal)
