what is this spider? i have seen it during the night and it stood still when i pointed light at it, then when i removed the light it flew away in an instant. I managed to get it under light again, it stopped again and then i took some photos of it. I took a look around for spiderwebs but i think i only saw one fresh one which was short and like a double string. I have also found irregular old webs with lots of dust along the ceiling. The room where i have seen it is used everyday however it probably came out of a wooden shelve which is rarely used.
