Spider Building its Web - Bob Armstrong's Nature Alaska

https://vimeo.com/345033798

Spider Building its Web was filmed on June 27, 2019 in Juneau, Alaska.
It was doing this about 10 p.m. under a light that was on all night.
The next day I looked at the web and it had caught loads of tiny insects that appeared to be no-see-ums and biting black flies.
The spider was tentatively identified by Joey Slovik as Tetragnatha versicolor a species of Long-jawed Orb Weavers.
To learn more about these spiders look at https://animaldiversity.org/accounts/Tetragnatha_versicolornomic Tetragnatha versicolor eats pest insects,
According to this article this spider has a positive importance to humans because it eats insects that bite us.
