Spider Question...........how did it make this web?
No photo.........sadly window cleaner came before I could photograph it
Outside our patio door we have a pergola and the 2 wooden upright end posts are approx. 900mm apart.
The spider managed to get a thread from left post to right post then another approx 300mm below that one....... then form a beautiful web approx 300 diameter between those posts.
So........how could it get the initial threads across the span??
The only way I can think is to allow the wind to carry it.......but that is some feat of engineering.
