Grå sektoredderkop (Zygiella x-notata)
Den grå sektoredderkop er nærmest en synantrop. Den findes oftest på eller i bygninger, hvor den virker til at have en særlig forkærlighed for vinduesrammer.
Artens spind er karakteristisk, da det ligner et klassisk rundt spind; men der mangler en kile-sektion, hvor der i stedet er en signaltråd fra spindets midte og ud til edderkoppens observationspost udenfor nettet.
Arten kan ses aktiv hele året, så længe frosten ikke er sat ordentligt ind.
Missing Sector Orb-weaver (Zygiella x-notata)
The Missing Sector Orb-weaver is close to being a synanthropic species. It’s usually found on or inside buildings and it seems particularly fond of window frames.
The web of this species is very characteristic as it resembles the classic orb-web missing a wedge-shaped sector of the web. Instead, there is a signal thread from the center of the web to the spiders perch just outside the web itself.
This species can be found all year as long as the temperture doesn’t drop too far below freezing for longer periods during the winter.
